Aiming at the impact of high current produced by motor starting on power grid and the influence of starting torque on motor performance,the intelligent motor control system based on DSP digital signal processor is studied in this paper. The system uses thyristor voltage regulation mode,through the PID control unit,to achieve the stator voltage ramp start and current limiting start,and in the process of parking to achieve the motor soft stop function. Through the analysis and design of the circuit structure and control program of the control system,the application of PID control algorithm based on depth learning in the motor control system is completed. The real-time adjustment of PI control parameters is realized by using the running voltage and current signals of the motor,and the stable operation of the motor is guaranteed. The research content of this paper is of great significance for the promotion and efficient utilization of intelligent motor.
