CENG 471 - Process Control Lab

Spring 2000

PART III: PULSE TEST

1. Use the experimental data from the pulse test to compute the frequency response of the system (Download the file with the pulse test data from the course web site). Fit the frequency response to obtain the transfer function of the process.
   
   
2. Draw the block diagram of the control system and place in each block the appropriate transfer function.
   
   
3. Compute the ultimate gain and ultimate period for this new control system.
   
   
4. Use all the methods you know that will give you PI or PID controllers for this process.
   
   
5. Write a SIMULINK program to compare the performance of these controllers for setpoint changes from 1.0 to 2.0 g/l using the IAE, ISE and ITAE indices.
   
   
6. Find the controller design that minimizes the amount of off-spec product after a setpoint change.
   
   
7. Use a trial-and-error procedure to design a controller with better performance than the controller you designed in Part 6 above.

Reminder on Honor Code Policy: "The students may talk to each other, the labbies or the instructor about any assignment in the course that is not specifically designated as pledged. This assistance is limited to the discussion of the problem. Consulting another student's solution (even from a previous class on the same subject) is prohibited, and submitted solutions may not be copied from any source."
