DC SERVO MOTOR CONTROL SYSTEM

摘要

PURPOSE:To obtain a servo system which can be controlled to be accurately positioned at a high speed by using both a feed-forward control and a feedback control. CONSTITUTION:A first memory area 21A stores data of optimum input time series for controlling in a shortest time. The data of the time series is used for a feed-forward control. A second memory area 21B stores data of optimum output time series. A pulse signal output from the encoder or the like of a DC servo motor is sampled at a high speed, a calculation with P (proportion), I (integration), D (differentiation) is executed with data of the optimum output time series stored in the area 21B, and the forward control is corrected with the data of the optimum time series by the calculated result.
