摘要: 传统的基于PI的永磁同步电机(PMSM)控制存在调节时间长、超调量大、适应性差等问题。因此，本文采用了一种基于FLC和PI的闭环SVPWM控制系统。该系统可以提高速度并显著减少过冲量。FLC (Fuzzy Logic Controller)的两个输入是转速误差和转子或主轴的误差变化率。模糊控制器根据MF (Membership Function)和模糊规则进行推理和去模糊。该逻辑算法最终输出一个信号以实现FLC控制。在MATLAB/Simulink中对基于模糊PI的PMSM闭环SVPWM控制系统进行建模和仿真。在仿真实验中，经过与不同工况下传统PI控制的对比分析，得出以下结论：基于FLC和PI的永磁同步控制器与传统PI算法相比，具有反应快、过冲可忽略不计、对变化具有更强的弹性等优点。
Abstract: Conventional PI-based permanent magnet synchronous motor (PMSM) control has problems such as long regulation time, large overshoot, and poor adaptability. Therefore, a closed-loop SVPWM control system based on FLC and PI is used in this paper. The system can improve both the speed and significantly reduce the amount of overshooting. The two inputs to the FLC are the rotation speed error and the rate of change of error for the rotor or spindle. The fuzzy controller performs inference and defuzzification according to the MF and fuzzy rules. This logic algorithm finally outputs a signal to achieve FLC control. A Fuzzy PI based PMSM Closed-loop SVPWM Control System is modeled and simulated in MATLAB/Simulink. In the simulation experiment, after comparing and analyzing with the traditional PI control under different working conditions, the following conclusions are obtained: the PMSM controller based on FLC and PI has the following strengths: fast reaction, negligible overshoot, and greater resilience to change compared to the conventional PI algorithm.
