ENG342: Laboratory Experiments Engineering Report Writing Assessment Answer

Assessment Task:

The experiments will focus on the learning about controlling the level of liquid in a tank. While we are specifically looking at level measurement and control, the principles that we learn through the experiments regarding PID control is transferable to other systems such as flow and temperature control. The laboratory activities over the residential period are described below. The practical exercises indicated below can be found in the accompanying pdf document Manual Chapter 7.pdf.

Session 1
1. Familiarisation of equipment used for the experiments
Demonstration of how to use the equipment, change set points, valve positions, etc. by Maung Maung Soe.

2. Level control loop: Proportional control (Practical Exercise 11)
a. Start with a level of 120 mm.
b. Adjust the control valve manually to achieve a steady state.
c. Set the proportional gain to 0.5.
d. Make a step-change in the set point of 20mm and set the valve to automatic control.
e. Record the results and your observations.
f. Make sure that you collect data on valve position, level and time when a step change in setpoint was made so that you have the necessary data for your analysis.
g. Repeat the experiment with two different Kc values. Choose the Kc values based on your observations so that you are trying to achieve different controller
response.

Session 2
1. Level control loop: PI control (Practical Exercise 12)
a. Adjust the valve manually to achieve steady-state at a level of 120mm.
b. Based on your observations in step 2 of session 1, choose a value for Kc.
c. Choose ti = 0.1.
d. Make a step-change in the set point of 20mm and set the valve to automatic control.
e. Record the results and your observations.
f. Repeat the experiment with two different ti values (keep Kc the same). Choose the ti values based on your observations so that you are trying to achieve different controller response.

2. Level control loop: PD control

a. Adjust the valve manually to achieve steady-state at a level of 120mm.
b. Based on your observations in step 2 of session 1, choose a value for Kc.
c. Choose td = 0.5.
d. Make a step change in the set point of 20mm and set the valve to automatic control.
e. Record the results and your observations.
f. Repeat the experiment with two different td values. Choose the td values based on your observations so that you are trying to achieve different controller response.

3. Level control loop: PID Control (Practical Exercise 14)
a. Adjust the valve manually to achieve steady-state at a level of 120mm.
b. Based on your previous observations, set values for Kc, ti and td.
c. Make a step change in the set point of 20mm and set the valve to automatic control.
d. Record the results and your observations.
e. Repeat the experiment with two different combinations of Kc, ti and td.
Choose the td values based on your observations so that you are trying to achieve different controller response.

Session 3
1. Controller tuning using Reaction Curve Method
a. Carry out the experiment outlined in the Edibon manual (Practical exercise 15)
b. Calculate the PID parameters using the Process Reaction Curve method with the equations provided in the manual.

2. Assess controller performance
a. Set the controller parameters to the values estimated from the reaction curve method.
b. Introduce a step change by changing the set point of the level.
c. Observe and evaluate the performance of the level controller.
