ELECTRIC MOTOR CONTROL SYSTEM

摘要

An electric motor control system capable of reducing torque pulsation resulting from an intermittent control and assuring a smooth acceleration/deceleration. In a speed reference signal converter, a deviation between a last time value .omega.r-1 and a this time value .omega.r of the speed reference signal .omega.r of a master control system is computed, the speed reference signal .omega.r from the master control system is converted into a speed reference signal .omega.r* conforming to the computing cycle of the motor control system according to a ratio between the updating cycle of the speed reference signal from the master control system and a computing cycle in a motor control system and said deviation, a motor driving signal is produced according to this converted speed reference signal .omega.r* and a motor is driven.
