摘　　要：为了提高矿用永磁同步电机的抗干扰能力,针对永磁同步电机逆变器中传统SVPWM(电压空间矢量)算法的缺陷性,采用非正交坐标系下算法,与传统SVPWM算法相比该方法简化了矢量算法步骤。速度外环采用模糊PI控制器,在线调整PI控制器中的参数,增强系统的鲁棒性。通过Matlab/Simulink建立仿真模型,仿真结果表明非正交坐标系下模糊PI永磁同步电机系统具有更好的稳定性和抗干扰能力,具有良好的性能。In order to improve the anti-interference ability of permanent magnet synchronous motor（PMSM）,and overcome the defects of the traditional space vector pulse width modulation（SVPWM）algorithm applied to PMSM inverter,the algorithm based on non-orthogonal coordinate system is adopted. In comparison with the traditional SVPWM algorithm,the steps of the proposed algorithm are simplified. The fuzzy PI controller adopted by the outer loop to control the speed is used to adjust the parameters in PI controller and improve the system robustness. The simulation model was established by means of Matlab/Simulink.The simulation results show that the PMSM system with fuzzy PI controller based on non-orthogonal coordinate system has superior stability and anti-interference ability,and good performance.
