PURPOSE:To improve frequency response and suppress natural oscillation in mechanical system exactly, by fetching the proportional operation of a speed control loop in the operational cycle of current control, and by processing the operation with a quick cycle. CONSTITUTION:A speed control loop A is composed of an integral term 1/S and a proportional term gain Kp, and a current control loop B is also formed with a proportional integrating element PI. A control element D including the proportional term gain Kp of the speed control loop A and the current control loop B formed with the proportional integrating element PI, in the speed control system is processed with the operational cycle of the current control of a micro- processor. In this manner, an only proportional element influencing the load response of the speed control loop quickly is processed with the same quick operational cycle as that of the current control, and so frequency response can be improved. |
