Instructors and students are asked to choose from a variety of controller design options. The following are suggestions: IMC-based PID, Ziegler-Nichols (and Tyreus-Luyben), and frequency response.
For the selected controller design technique, perform simulations for the following:
A level setpoint change of 0.1 (dimensionless) at t = 1 minute.
A steam demand change of 0.5 (dimensionless) at t = 1 minute.
In each case discuss the effect of controller tuning. In addition to the response of stream drum level (process output), include plots of the manipulated input (valve position). You may wish to revise the SIMULINK diagram shown in Appendix M9.1, for your simulations.
Use the IMC-based PID procedure ...
