Abstract
This paper investigates the issue of load disturbances in DC motor speed regulation systems. In response to the limited disturbance rejection capability of traditional PID controllers, a PID controller with feedforward compensation is designed. The study first analyzes the dynamic impact mechanism of sudden load changes on motor speed, and then achieves precise control of the DC motor using PWM technology. Through comparative analysis of simulation and experimental results, the proposed feedforward-compensated PID control demonstrates significant improvements in dynamic response speed, overshoot, and steady-state accuracy compared to traditional PID control. The findings indicate that the proposed control strategy effectively suppresses load disturbances, enhances system stability and robustness, and offers valuable insights for practical engineering applications.
