PI controller with limited output, anti-windup compensation,
setpoint weighting, optional feed-forward and optional freezing of
the state
The following features are present:
- The output of this controller is limited. If the controller is
in its limits, anti-windup compensation is activated to drive the
integrator state to zero.
- Setpoint weighting is present, which allows to weight the
setpoint in the proportional part independently from the
measurement. The controller will respond to load disturbances and
measurement noise independently of this setting (parameters Wp).
However, setpoint changes will depend on this setting.
- Optional feed-forward. It is possible to add a feed-forward
signal. The feed-forward signal is added before limitation.
Extended with Freeze functionality: If boolean
input is set to true, the derivative of the state variable is set
to zero.
