Abstract
The possibility of replacing the classic PI controller with a fuzzy controller for the existing system of automatic control of the rotor speed of a permanent magnet synchronous motor without a position sensor is considered. The use of PI rotor speed controllers for a permanent magnet synchronous motor has several disadvantages that should be taken into account when designing and operating such systems. Such controllers require careful adjustment of the coefficients to achieve the desired performance, they may be sensitive to changes in system parameters such as winding resistance or inductance, and they may have limited ability to respond to rapid and large load changes. The use of a fuzzy controller eliminates a number of disadvantages of the PI controller. The architecture of the proposed fuzzy controller is standard: a fuzzifier, a block of rules, and a defuzzifier. The fuzzy controller is of the Sugeno–Takagi type. The fuzzifier is based on triangular term sets, defuzzification is performed using the weighted average method. The number of fuzzy controller parameters has been optimized. The simulation was performed in the MATLAB/Simulink package, taking into account the changing load on the motor and changing motor parameters. The results obtained confirm the possibility and feasibility of replacing the PI controller with a fuzzy controller.
摘 要 在现有的无位置传感器永磁同步电机转子速度自动控制系统中，考虑了用模糊控制器取代传统 PI 控制器的可能性。永磁同步电机转子速度 PI 控制器有几个缺点，在设计和运行此类系统时应加以考虑。此类控制器需要对系数进行仔细调整，以达到所需的性能；它们可能对绕组电阻或电感等系统参数的变化很敏感；它们对快速和巨大负载变化的响应能力可能有限。模糊控制器的使用消除了 PI 控制器的一系列缺点。拟议模糊控制器的结构是标准的：一个模糊器、一个规则块和一个解模糊器。模糊控制器属于 Sugeno-Takagi 类型。模糊器基于三角形项集，去模糊化采用加权平均法。模糊控制器参数的数量已经过优化。仿真是在 MATLAB/Simulink 软件包中进行的，考虑到了电机负载的变化和电机参数的变化。结果证实了用模糊控制器取代 PI 控制器的可能性和可行性。
