The simulations shown in Plant Outputs for T Setpoint Scenario with Added Data
Markers and Plant Inputs for the T Setpoint Scenario uses the default controller
settings. These often work well, but the CSTR application is an exception. The following
discussion covers the main controller options in detail, and shows how to tune a
controller for better performance.
This section covers the following topics:

Model and Horizons
Select your MPC1 controller in the tree. The view shown in Controller Options — Model
and Horizons Tab should appear. If necessary, click the Model and Horizons tab to
bring it to the front. This tab contains the following controller options:
