Feedback Control Systems Assignment | Homework For You
Feedback Control Systems Laboratory (ECCE 415) Pre-Lab Activity/Assignment No. 2 In experiment 3, you will be required to control the temperature inside a chamber by providing a control signal to a heater. Although this process is complicated, several assumptions allow to obtain a model that represents the dynamics of the process to an acceptable degree.
Figure 1 shows the block diagram of the Simulink file provided to you. B Figure 1. Simulink block diagram of the chamber heater experiment.
1. Use the manual switch to select the relay control and observe the output.
2- Comment on the effect of changing the “switch on” and “switch off” points in the relay block settings) to 1 and -1 respectively.
3. What happens to the output when the “switch on” and “switch off” points are changed to 0 (you may need to zoom in)? Is this good for the system?
4- Return the “switch on” and “switch off” points to 2 and -2. Add an offset of 0.1 to the relay output. Comment on the change of the system behavior.
5. Compare the response with relay control to that of PI control.
6- How does the parameter bsp affect the transient response? Compare values of 0.1 and 1. Make sure to provide plots and brief answers. Get Computer Science homework help today
