Some control applications require the controller to select control actions such that the plant states do not violate certain critical constraints. In many cases, the constraints are on plant states that the controller does not control directly. Instead, you define a constraint function that defines the constraint in terms of the control action signal.
Simulink® Control Design™ software provides the Constraint Enforcement block for such applications. This block uses Optimization Toolbox™ software to compute the modified control actions that are closest to specified control actions subject to constraints and action bounds.
