MOTOR CONTROLLER

摘要

PURPOSE:To stabilize a control system or enhance a band frequency by controlling a motor by alternately using a detected value and a predicted value of angular velocity of the rotation of motor. CONSTITUTION:Angular velocity storage means 4 stores a detected value obtained at each period T by angular velocity detecting means 2. Torque storage means 5 stores a torque command value decided at each period T/2 by control means 3. Angular velocity predicting means 6 calculates to predict a rotating angular velocity, of rotation of a motor by using the stored values of the means 4, 5. The means 3 decides a torque command by using the detected value of the means 2 and the predicted value of the means 6.
