ABSTRACT:
In a stability compensating circuit of an actuator system which has an actuator that is actuated in response to an input signal and has an object to be controlled by the actuator and includes a vibrational component and wherein the stability of the actuator system is compensated by controlling a deviation signal between the input signal to the actuator and a feedback signal from the actuator, the improvement comprising a moving average filter for averaging the deviation signals to the actuator at intervals of a moving average time of the filter.
