Abstract
A speed instruction generation apparatus of a motor interpolates a first position instruction to obtain a second position instruction. The second position instruction is a second-order continuous instruction. The second-order continuous position instruction is differentiated two times to obtain a compensation speed. The speed instruction generation apparatus further generates a first speed instruction according to a difference between an actual position value of the motor and the second position instruction. The first speed instruction is added to the compensation speed to obtain a second speed instruction to control a rotation speed of the motor.
