All students of the group would be considered as having committed an act of plagiarism irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all the students of the group. If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and MEC_AMO_TEM_035_02 Page 8 of 10 Control and Instrumentation 1 (ENGG 0009.1) – Spring - 21 – CW 2 (Assignment 2) – A – QP the penalty will be applied as per the policy for each student according to his / her history of violation. Type 4: Variation of Type 1 and Type 2: In cases where the assessment consists of components or part submissions that could be a group assessment component (e.g. group assignment) and an individual assessment component (e.g. individual reflection), the following will be applicable: a. If plagiarism is detected in the group assessment component, all students of the group will be considered as having committed an act of plagiarism, irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all students of the group. In such cases the group assessment component will be resubmitted. If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and the penalty will be applied for each student according to his / her history of violation. b. If plagiarism is detected in the individual assessment component, the individual assessment component will be resubmitted - if the student is eligible for resubmission-. The policy will then be applied to that student alone. c. In both cases (a) and/or (b), the deduction in marks will be applicable for the whole assessment (assignment). 1.7. Types/Variation of Cases of Multiple Offences If student is caught with multiple violations of same or different nature in different modules of the same semester, they will be considered as one offence and student will be penalized for each violation according to the type of the offence. If student is caught with multiple violations of same or different nature in the same module of the same semester, then they will be considered as different offences and each will contribute to the overall count of AIV. The student then shall be penalized for each violation according to the count and type of each offence. * For further details Refer to MEC Student Academic Integrity Policy in Student Handbook. 2. Late Submission Regulations: It is the students’ responsibility to check all relevant timelines related to assessments. As per the Assessment Policy at MEC, late submissions are allowed for one week (5 working days) for all UG modules with a penalty. In such cases, a deduction of 5% of the marks obtained for the submitted work shall be imposed for each working day following the last date of submission till the date of actual submission. Assessment documents submitted beyond a period of one MEC_AMO_TEM_035_02 Page 9 of 10 Control and Instrumentation 1 (ENGG 0009.1) – Spring - 21 – CW 2 (Assignment 2) – A – QP week (5 working days) after the last date of submission will not be accepted and will be awarded a zero for that assessment. In cases where the submission has been delayed due to extenuating circumstances, the student may be permitted to submit the work without imposing the late submission policy stated above. The extended period of submission will be one week from the original last date of submission. In such cases, the student is expected to submit the supporting certificates on or before the original last date of submission of the assessment and the decision of extension rests with faculty responsible for the assessment .The late submission policy shall be applied if the student fails to submit the work within one week of the original last date of submission.

Type 2: In case plagiarism is detected in a group assessment, all students of the group will be considered as having committed an act of plagiarism irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all students. If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and the penalty will be applied as per the policy for each student according to his / her history of violations. Type 3: Combination of Type 1 and Type 2: In case plagiarism is detected in any component or part submission (submitted at different times) of a group assessment (assignment), the deduction in marks will be applicable for the whole assessment (assignment), even if only the component or part submission alone needs to be resubmitted. All students of the group would be considered as having committed an act of plagiarism irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all the students of the group. If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and MEC_AMO_TEM_035_02 Page 8 of 10 Control and Instrumentation 1 (ENGG 0009.1) – Spring - 21 – CW 2 (Assignment 2) – A – QP the penalty will be applied as per the policy for each student according to his / her history of violation. Type 4: Variation of Type 1 and Type 2: In cases where the assessment consists of components or part submissions that could be a group assessment component (e.g. group assignment) and an individual assessment component (e.g. individual reflection), the following will be applicable: a. If plagiarism is detected in the group assessment component, all students of the group will be considered as having committed an act of plagiarism, irrespective of whether plagiarism is on account of the act of all or a few or only one member. The policy will then be applied to all students of the group. In such cases the group assessment component will be resubmitted. If some students in the group are eligible to re-submit (first offence) and others are not eligible, only eligible students will be allowed to re-submit within a period of one week and the penalty will be applied for each student according to his / her history of violation. b. If plagiarism is detected in the individual assessment component, the individual assessment component will be resubmitted - if the student is eligible for resubmission-. The policy will then be applied to that student alone. c. In both cases (a) and/or (b), the deduction in marks will be applicable for the whole assessment (assignment). 1.7. Types/Variation of Cases of Multiple Offences If student is caught with multiple violations of same or different nature in different modules of the same semester, they will be considered as one offence and student will be penalized for each violation according to the type of the offence. If student is caught with multiple violations of same or different nature in the same module of the same semester, then they will be considered as different offences and each will contribute to the overall count of AIV. The student then shall be penalized for each violation according to the count and type of each offence. * For further details Refer to MEC Student Academic Integrity Policy in Student Handbook. 2. Late Submission Regulations: It is the students’ responsibility to check all relevant timelines related to assessments. As per the Assessment Policy at MEC, late submissions are allowed for one week (5 working days) for all UG modules with a penalty. In such cases, a deduction of 5% of the marks obtained for the submitted work shall be imposed for each working day following the last date of submission till the date of actual submission. Assessment documents submitted beyond a period of one MEC_AMO_TEM_035_02 Page 9 of 10 Control and Instrumentation 1 (ENGG 0009.1) – Spring - 21 – CW 2 (Assignment 2) – A – QP week (5 working days) after the last date of submission will not be accepted and will be awarded a zero for that assessment. In cases where the submission has been delayed due to extenuating circumstances, the student may be permitted to submit the work without imposing the late submission policy stated above. The extended period of submission will be one week from the original last date of submission. In such cases, the student is expected to submit the supporting certificates on or before the original last date of submission of the assessment and the decision of extension rests with faculty responsible for the assessment .The late submission policy shall be applied if the student fails to submit the work within one week of the original last date of submission. Students may contact their teachers for clarification on specific details of the submission time if required. 3. Research Ethics and Biosafety Policy To protect and respect the rights, dignity, health, safety, and privacy of research subjects involved including the welfare of animals and the integrity of environment, all student projects are expected to be undertaken as per the MEC Research Ethics and Biosafety Policy. Accordingly the following shall apply.  Research and other enterprise activities shall be conducted by maintaining the high ethical standards consistent with national and international standards and conventions.  Any research at MEC that is categorized as high-risk research shall be subject to review and approval by the Research Ethics and Biosafety Committee.  Research activities involving collection of human or animal tissues and manipulation of microbial, animal or plant cells shall be subject to review and approval by the Research Ethics and Biosafety Committee.  Participants involved in research must be informed about the purpose of research and intended uses of research findings. Written consent must be obtained from people involved prior to the commencement of research.  Data obtained from participants must be treated with high confidence and should be used only for the intended purpose of research. MEC_AMO_TEM_035_02 Page 10 of 10 1 TASK 1: Proposal Aim: This proposal contains the formulation of how the control system and its implementation been done using the Matlab functions and PIDTuner and PID. Proposal Overview: The efficiency of a system is measured by the effect of disruptions such as "disruption rejection of the system," which can be resolved. The spinoff word should be a small price because its susceptibility to noise causes uncertainty, and even with interference it should oscillate very little [6]. The response time or increasing time of the PID controller does not exceed a pair of prices with an associated degree of volatility. In addition, peak time can succeed in the system's height price comparatively or substantially quickly. In order to mitigate error e(t) within the device over time, PID control terminology should either have to be as small as possible or to close as zero as possible [5] The component summarizes the time of the error. Although a minute short error term will eventually increase the integral component which will continue to increase if this error is zero. The constraint is observed here as an integral connection, which occurs until the integral operation is saturated and does not lead the error to zero any longer between the pointer variable. In this proposal, with the application of all tasks to be completed in the task 2 section, we can learn how to execute the Matlab functions for the control system design and the application of PID and PIDTuner windows and also, on how open it using Matlab command. 2 TASKS TASK 1 PROPOSAL TASK 2 Questions 1 Part A Part B Part C Question 2 Question 3 Part A Part B Question 4 Part A Part B Part C Part D Tasks Timeline for completion APRIL MAY 1 2 3 4 16 17 18 19 20 21 22 23 3 TASK 2: Questions & Answers Q 1: Strain Gauge Part a: The equations loop equations.

Strain is the variation in proportions due to a used force commonly as a length difference, a neutral direction displacement, or a volume differential. There is then a strain on the wires in a strain gauge attached to the stretched or straining portion. The wires would also decrease in the cross-section surface if the tension is extended. Since a wire's resistance is proportional to its length and inverse to its cross-sectional area, the resistance of the two-wire is increased if a wire is expanded [5]. The stress in the strain gauge adjusts its resistance and the voltage changes across or current across the wires of the strain gauge is used to test its resistance. The output voltage of the Wheatstone bridge, used in the strain gauge, is directly proportional to the source voltage applied to the Wheatstone bridge. The normal range of source voltage is 5-12 volts. The general practice is to keep the source voltage at a lower value to avoid self-heating of the strain gauge wire. If the source voltage will be high, then it will beat up the strain gauge wire. This causes error in measurement. 6 Q 2: “ T h e operation and importance of instrumentation sensors and transducers used in the chemical process shown in figure 2” Figure 2 Discussion: Toluene and certain quantities of hydrogen enter a conversion mechanism where it produces methane and certain quantities of benzene. One thing to think about is that the chemical reaction is incomplete and hence it is necessary to add a chemical called "toluene." The gasses that cannot be condensed are split and exhausted. The generated benzene comes from the same substance and the non-reacting toluene is subsequently separated by the method referred to as distillation. We must also realize that toluene can be used in the special reactor system again and, thus, the expended supply of benzene is isolated and is mostly referred to as 'steam" [3]. We all need to realize that 7 the block-based process leads us to innovate novel products and related substances. It helps one to get to know all the facts found in one's eye and we do not read all the historical material of the related operation. Furthermore, our mission is much simpler so we can save our time. The research team may also concentrate further on the primary developmental pain points and infer parameters that most influence a system, such as the pressure variable or the temperature variable, or overall heater-related parameters. The concept "process control" is one of the main words in the field of chemical engineering. The use of devices operated by related mechanical and electronic subsystems, mainly known as Automatic control, is the main objective of this procedure [1]. This method is designed to maintain the current operating conditions as specified by the consumer and to be highly efficient at the same time. This method aims at keeping the process in progress on the operating conditions specified by the consumer, while simultaneously being highly efficient and bringing into the environment a much smaller volume of toxic matter with a certain increase in product properties. The P&ID diagram shows that feedstock 1 and feedstock 2 are fed into the reaction chamber independently via the V1 and V2 valves. The reactor is also supplemented with water through the V3 valve. Both V1 valves are automatically equipped with V2-V3 (and even V4) valve actuators. The valves are controlled by the USB interface module's discrete digital display. The USB module receives a signal from a computer with a program that interprets and takes the appropriate actions the data obtained from the USB interface module: The data obtained from the USB interface module is transmitted by the various analog inputs that sensors the reactor level, pressure, and temperature. The measures required by the PC to transmit a signal to the USB interface module include Valves V1, V2 and V3 opened and closed according to reactor conditions. The stirrer is used to start, stop and increase or decrease the rpm. The agitator function will here be used to properly combine the components following the time interval set or by reading the reactor conditions based on program logic. 8 A control system, particularly a closing loop system, is important for the maintenance of a product with the required quality and quantity. A standard value is initially entered on a control loop and the calculated parameter by the separate sensor is also fed into the control loop [2]. If an error is produced, and the error value is named by giving appropriate feature feedback to the inputs, the calculated value compares with the standard value. Physical conditions valve and adjustment. An interface module is needed to execute the control logic [5]. A USB module is used in this case. It is supplied with different sensor calculated parameters and also implemented closed-loop control logic. The interface consists of a module for microcontrollers. To track this plant, all parameters must be seen on the computer, a PC can be used for this purpose. Typically a process engineer carries out this part. This component often has warnings to alert in the event of an accident/danger scenario [6]. 9 Q3: Uncompensated system (𝑠) = 150 (𝑠 + 7𝑠 + 40) 2 Figure 3: Uncompensated system Part a: Application of PID tuner and tune the PID controller Matlab Code: Output of using PID: Now, to open the PIDtuner, let us use the command: pidTuner(G) 10 Next is to change it to PID in type as shown below: Now, let us apply or use the command: Tuning tools --> Show parameters in order to view parameters of the system as shown below: 11 We can see an overshot = 0 after setting the second slider, and a setting time = 0.763 s, which perfectly fits into the parameters of our design. You can play with sliders in this way if you want to better your efficiency (first increase response time, then decrease overhead). 12 Part b: “The usefulness of PID tuner is in designing and evaluating the performance of control processes.” Matlab Code: Output: 13 PID tuner/controllers are very useful in designing and assessing control process efficiency as they evaluate process output and control the input by keeping the output at the desired value (also called as set point). In many industrial applications, the most typical example of a PID controller is temperature control [3]. Based on the output, the system we designed is very useful for the controller system design since it is within the within design specifications, and in fact PID tuner. 14 Q4.

Figure 4: Basic Satellite launching system 18 Figure 5: Basic Satellite launching system with unity feedback For the design and implementation of reliable control system design for single input output systems, SISOTOOL is stronger. It contains dynamic plot Bode, root locus plot, performance reaction and plot Nichols. By using this graphical editor, the controller builder can quickly add, change and delete poles, zeros and gains. SISOTOOL offers either graphically or numerically the ability to insert and change poles and nulls and each mode has its own advantages [3]. It is beneficial to add them numerically if specific values are needed (for example a pole at the origin for a controller with Integral term). By graphically adding (and moving) the user may make changes in order to determine the control setup which can allow the root locus to move around the desired poles roughly. 19 References [1] Leehter Yao and Chin-Chin Lin, Design of Gain Scheduled Fuzzy PID Controller, World Academy of Science, Engineering Technology, 2005.

TASK 1: Proposal

Aim: This proposal contains the formulation of how the control system and its implementation
been done using the Matlab functions and PIDTuner and PID.
Proposal Overview:
The efficiency of a system is measured by the effect of disruptions such as "disruption rejection of
the system," which can be resolved. The spinoff word should be a small price because its
susceptibility to noise causes uncertainty, and even with interference it should oscillate very little
[6]. The response time or increasing time of the PID controller does not exceed a pair of prices
with an associated degree of volatility. In addition, peak time can succeed in the system's height
price comparatively or substantially quickly. In order to mitigate error e(t) within the device over
time, PID control terminology should either have to be as small as possible or to close as zero as
possible [5]
The component summarizes the time of the error. Although a minute short error term will eventually
increase the integral component which will continue to increase if this error is zero. The
constraint is observed here as an integral connection, which occurs until the integral operation is
saturated and does not lead the error to zero any longer between the pointer variable.
In this proposal, with the application of all tasks to be completed in the task 2 section, we can
learn how to execute the Matlab functions for the control system design and the application of
PID and PIDTuner windows and also, on how open it using Matlab command.

As shown in the output on part b, we noticed that there is a linear relationship between the voltage
reading and the strain gauge resistance. Strain is the variation in proportions due to a used force
commonly as a length difference, a neutral direction displacement, or a volume differential. There
is then a strain on the wires in a strain gauge attached to the stretched or straining portion. The
wires would also decrease in the cross-section surface if the tension is extended. Since a wire's
