Design Controller in Simulink
5-5
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.
