ABSTRACT:
An electric servo system has an electrical drive and a controllable object driven by the electrical drive whereby an error between an actual amount of actuation of the controllable object and a target value toward which the object is controlled is applied to the electrical drive to control the same so that the amount of actuation of the controllable object coincides with the target value. A compensator is provided on the input side of the electrical drive, for compensating the load characteristics of the controllable object such that the output of the electrical drive does not have apparent dependency on torque of the load.
