Abstract: A closed loop motion control system employing at least one relaxor actuator which controls the position of a moving member having mass by controlling an electric field applied to the relaxor actuator. The actuator comprises a body of relaxor material dimensionally variable under the influence of the electric field applied in the form of a voltage to electrodes on at least two surfaces of the actuator. The voltage is applied in response to a feedback signal produced by at least one feedback sensor, which may be a displacement sensor or some other type of sensor. Thus, by constantly monitoring the displacement or other variable of the actuator device, the position of the moving member may be precisely controlled.
