ABSTRACT:
A motor servo system is disclosed which is capable of accomplishing the precise control of a set point of a mechanical element to be controlled without particularly considering the mechanical connecting condition between a motor and the mechanical element and being readily accommodated to a variation of the set point and a variation of overshoot due to a variation of load. The motor servo system is constructed in a manner such that a controlled set point of a controlled element such as a mechanical element is independently set by means of a time signal generating section preceding a servo circuit section.
