A MOTOR SPEED CONTROL APPARATUS |
摘要 |
<p>The motor speed control apparatus according to the present invention controls the rotation speed of a motor to be constant in a state where a disturbance torque is present. The motor speed control apparatus includes a disturbance torque observer 1. The disturbance torque observer 1 estimates a disturbance torque tau d based on a detected speed signal v detected by a speed detector 105 and a drive signal D supplied to a drive circuit 150, and cuts off high-frequency components thereof by means of filters 13 and 2 so as to output an estimated disturbance signal d. A comparator 130 outputs a speed error signal DELTA v, which is a difference between the detected speed signal v and a desired speed signal vr. An arithmetic unit 140 outputs a control signal c in accordance with the speed error signal DELTA v. A torque correction unit 3 corrects the control signal c by using the estimated disturbance signal d so as to output the drive signal D. The drive circuit 150 supplies a motor 100 with a drive current Ia which is in accordance with the drive signal D.</p> |
