Abstract
A rotation speed control method and device of a motor, and a motor control system; the rotation speed control method of the motor comprises the following steps: conducting differential regulation on the output rotation speed of the motor to generate a feedback rotation speed signal (S1); generating a rotation speed deviation signal according to a target rotation speed signal and the feedback rotation speed signal (S2); conducting proportional integral regulation on the rotation speed deviation signal to generate a rotation speed control signal (S3); and controlling the rotation speed of the motor according to the rotation speed control signal (S4). The rotation speed control method, the rotation speed control device and the motor control system run steadily and have good dynamic performance, and are easy to implement.
