Abstract
In a servo system using a discrete signal relative to a position, a time delay and an error upon detecting a speed due to lack of positional information are eliminated to achieve a positioning to a target position in a short time. A pulse signal X.sub.P relative to a position is used to establish synchronization with an observer which is adjusted to match with an actual apparatus comprising a load, a motor and so on, and an estimated speed value or an estimated position value generated by the observer are used to determine an operating signal for the servo system.
