Abstract
With the continuous development of industrial automation technology, the performance optimization of motor speed control system has become a key link to improve production efficiency and reduce energy consumption. Brushless DC motor is widely used in many fields because of its high efficiency, high torque density and good response characteristics. However, the traditional motor speed control system, such as PID control, often shows poor control effect and slow response speed in the face of nonlinear, time-varying parameters and load changes and other complex conditions. Therefore, it is of great significance to explore a new control strategy to optimize the motor speed control system. This paper focuses on the optimization of motor speed regulation system based on fuzzy logic, aiming to improve the performance of motor speed regulation system by introducing fuzzy control algorithm. Fuzzy control, as an intelligent control method, can effectively deal with the uncertainty and fuzziness in the control system, and has significant advantages in improving the robustness, stability and response speed of the system. This paper firstly introduces the basic principle and key technology of fuzzy control algorithm, including fuzzy set, fuzzy rule and fuzzy inference. Then, combined with the characteristics of brushless DC motor, a motor speed regulation system based on fuzzy logic is designed. The fuzzy controller is used to adjust the control parameters in real time to adapt to the change of the running state of the motor and achieve accurate speed control.
