ABSTRACT
As an essential component of modern industrial automation, the performance of motor speed control systems directly affects production efficiency and energy utilization levels. However, traditional PID control methods often fail to meet the requirements of high precision and rapid response under complex operating conditions. Therefore, introducing fuzzy control technology has become an effective approach to enhance system performance. This study aims to improve the dynamic performance and robustness of motor speed control systems by designing a fuzzy adaptive controller for permanent magnet synchronous motors based on fuzzy logic theory. This method constructs a fuzzy rule base and membership functions, enabling online adjustment of control parameters to adapt to load variations and nonlinear disturbances. Experimental results indicate that the proposed fuzzy controller demonstrates excellent tracking and disturbance rejection capabilities during startup, braking, and steady-state operation phases. Compared with classical PID control, the system overshoot is reduced by approximately 25%, and the settling time is shortened by about 30%. Moreover, the system maintains good stability under wide-ranging load fluctuations. Additionally, this research incorporates genetic algorithms to optimize the parameter configuration of the fuzzy controller, further enhancing control performance. This innovative improvement significantly strengthens the adaptability and intelligence level of the fuzzy control system. In conclusion, fuzzy control technology provides a flexible and efficient solution for motor speed control systems, possessing important theoretical significance and engineering application value.
