摘　　要：在永磁同步电机矢量控制系统中常选用传统模糊PI控制,但此种PI控制算法存在着转速跟踪效果差、转矩波动较大、对转速、转矩等控制精度不高等缺陷。针对这一系列缺陷问题,提出了一种新型融合积分环节模糊PI控制算法,并在仿真软件MATLAB/Simulink环境下验证结论。根据仿真结果表明:融合积分环节的新型模糊PI控制算法可显著提高整体控制系统鲁棒性,能达到高控制精度、快速响应的要求。In the permanent magnet synchronous motor vector control system,the traditional fuzzy PI control is often used.However,this PI control algorithm has the defects of poor speed tracking effect,large torque fluctuation,and low control precision such as speed and torque.Aiming at this series of defects,a new fuzzy integral PI control algorithm is proposed,and the conclusion is verified in the simulation software MATLAB/Simulink environment.According to the simulation results,the new fuzzy PI control algorithm integrating the integral link can significantly improve the robustness of the overall control system and achieve the requirements of high control precision and fast response.
