Abstract

PURPOSE:To eliminate the control response speed failure of a motor speed control system by connecting reverse function circuits of an inertial transfer function defined by a motor and its load and a transfer function of a current control system to a control system. CONSTITUTION:An AC motor having an actual speed value N driven by the control signal of a speed target N* is controlled through the transfer function 14 of a regulator for controlling the output of a supply power converter to the motor, a transfer function 15 of a current control system including a controller and a converter, and an inertial transfer function 11 determined by the motor and its load. In order to improve the response of the motor when the load is varied, the actual value N of the motor speed is applied to a circuit having the reverse function 16 of the inertial transfer function 11, the difference between the actual value and the output of the current control system is then obtained, the difference of the outputs is further applied to a circuit having the reverse function 17 of the transfer function 15 of the current control system, and this output is added to the output of the regulator.
