摘　　要：提出一种参数自整定模糊-PI控制器,用于永磁同步电机高频信号注入控制系统,模糊-PI控制器可以对自身PID参数通过控制器输入端口的误差的大小进行实时自适应调节,以达到减少输出的超调量以及调节时间,增强了系统的鲁棒性的效果。MATLAB仿真实验结果表明,加入模糊-PI控制的永磁同步电机高频信号注入控制系统比使用传统的PID控制系统在转速、转矩方面的控制性能都有较大的提高。A parameter self-tuning fuzzy-PI controller is proposed for the high-frequency signal injection control system of permanent magnet synchronous motor.The fuzzy-PI controller can adjust the PID parameters in real time according to the error to reduce the output.The overshoot and adjustment time enhance the robustness of the system.The simulation results of MATLAB show that the high-frequency signal injection control system of permanent magnet synchronous motor with fuzzy-PI control has higher control performance in terms of speed and torque than the traditional PID control system.
