Apparatus and method for controlling the position of a control object using a multi-stage actuator. A multi-stage actuator is provided with first and second actuation stages adapted to position a control object. A control circuit includes a multi-tap lattice structure and parallel first and second multiple regression filters coupled to respective taps of the multi-tap lattice structure. The control circuit concurrently generates and applies first and second disturbance rejection signals to the respective first and second actuation stages to compensate a disturbance signal component in a position error signal (PES) indicative of position error of the control object.
