| description | The invention discloses a device for accurately controlling the rotating speed of an alternating current servo motor and a control method thereof. The motor speed can be accurately and stably controlled. The circuit is simple in structure, speed acquisition, current acquisition, generation of three-phase complementary PWM and the like are realized through the master control single-chip microcomputer, and only few peripheral circuit modules need to be connected. The rotating speed of the motor is controlled through the digital pulse frequency generated by the digital pulse generator, and the digital pulse generator is simple. When the feedback speed of the motor is calculated, digital signal filtering processing is carried out, so that the rotating speed can be kept stable when the motor runs at a high speed. When feedback speed filtering and speed ring integral are calculated, decimal accuracy is reserved in the division operation process, and therefore accumulative errors are avoided.
