Web14.4.9.1 Feedforward Control. Feedforward control differs from feedback control in that the load or primary disturbance is measured and the manipulated variable is adjusted so that deviations in the controlled variable from the setpoint are minimized. The controller can then reject disturbances before they affect the controlled variable.
