Module 7. Biochemical Reactors

The objective of this module is to illustrate a practical problem where the IMC-based PID procedure can be used. The sections of the module are as follows:

M7.1 Background

M7.2 Steady-State and Dynamic Behavior

M7.3 Stable Steady-State Operating Point

M7.4 Unstable Steady-State Operating Point

M7.5 SIMULINK Model File

The procedure for a stable process will be used in Section M7.3, while the procedure for an unstable process will be used in Section M7.4. In both cases, use the SIMULINK model file presented in Section M7.5.

Although you will be using a linear controller, you will be implementing this controller on a nonlinear process. The inputs and outputs to/from this process are in physical variables, while the controller design procedure is based on deviation variables.
