ABSTRACT:
In a servo control apparatus wherein a load is controlled by a deviation between a command signal corresponding to a target value and a detected position signal of an actuator of a servo system and which has a plurality of the servo systems arranged in parallel with respect to the load, the servo control apparatus comprising: a forward circuit for producing a signal that changes in response to an external force exerted on the actuator; first feedback circuit for detecting the signal of the forward circuit and feeding the same back to the command signal; and second feedback circuit for feeding the detected position signal of the actuator back to the command signal, producing a deviation signal representative of a deviation between the position signal and the command signal, integrating the deviation signal, and inputting the integrated signal to the forward circuit.
