摘要
为了更好地解决电动汽车永磁同步电机的电流畸变现象,从而提高车辆运行稳定性,提出了一种基于自抗扰控制器的谐波抑制策略。使用自抗扰控制器取代传统PI控制器在电机电流环中的作用,通过补偿系统扰动的方式抑制谐波的产生,再与电机控制过程中的谐波抑制算法相匹配,提取出电机控制系统5、7次谐波并进行补偿。使用MATLAB/Simulink仿真并进行试验验证,结果表明,该算法更好地实现了谐波抑制功能,提高了车载永磁同步电机电驱系统的稳定性。
In order to better solve the current distortion of permanent magnet synchronous motors in electric vehicles,thereby improving vehicle drive stability,a harmonic suppression strategy is proposed based on active disturbance rejection controller.The auto-disturbance-rejection controller is used to replace traditional PI controller in the motor current loop and the harmonic wave is suppressed by compensation system disturbance.Combined with harmonic suppression algorithm in the motor control process,the 5 and 7 order harmonic are extracted and compensated.MATLAB/Simulink simulation and test results show that the algorithm can achieve better harmonic suppression and improves the stability of the permanent magnet synchronous motor system.
