This video (28 minutes) describes the principle of feedforward control, which can be used in addition to feedback control to obtain highly improved control by exploiting measurements of process disturbances and process knowledge in the form of a mathematical process model. Both feedforward from setpoint (reference) and from disturbance is covered by the video.
The video is based on the simulator Feedforward control of liquid level. (You may run the simulator while watching the video.)
