Abstract: In the design of the speed control system of pure electric tractor, the switched reluctance motor control system is introduced, and the PID controller is used to feedback the speed regulation process, so as to improve the sensitivity and accuracy of speed control, and make the speed control system have the ability of adaptive regulation. In order to verify the superiority of the switched reluctance motor control system based on PID, the speed regulation process of the control system is simulated, and two groups of different references are selected for comparison. The comparison results show that the control accuracy of the switched reluctance motor based on PID is better than the other two groups, thus verifying the reliability of its performance.
