Information

Proportional - Integral - controller with optional feed-forward and limitation at the output.

The integral part can be switched off to obtain a limited P-controller.

The feed-forward gain can either be constant or given by the optional input kFF.

When the output is limited, the controller cannot bring the control error to zero and the integrator will not stop integrating. To avoid this WindUp - effect, an Anti-WindUp loop is implemented: The difference between unlimited and limited output is fed back to the integrator's input.
