ABSTRACT:
A rotation control system includes a motor for driving a rotary body, a rotary encoder for detecting angular velocity of the rotary body, a CPU for controlling angular velocity of the motor via an interval counter and a motor driver based on the detected angular velocity of the rotary body. The CPU determines a transfer function of the rotation control system and then calculates gain and phase margins based on the transfer function. The CPU selects the most appropriate values of control parameters from preset values stored in a ROM when the gain or phase margin is out of a predetermined range.
