Design Controller in Simulink

For this example, use the default values of this dialog box. Click OK. The software

performs multiple tasks to design an initial MPC controller. These tasks include finding

an equilibrium operating point, linearizing the plant model, and building the MPC

controller. Finally, the Control and Estimation Tools Manager opens, containing an

MPC design task node (MPC Design Task - MPC Controller). This node includes the

linearized plant model, MPC open loop plant 1.

Evaluate Default Operating Point

The CSTR plant model has multiple equilibrium operating points. The software uses the

default equilibrium operating point to linearize the plant model. This operating point

could differ from the desired operating point. It is important to verify that the software

used an appropriate operating point. Otherwise, the linear plant model can be unsuitable

for controller design.
