摘    要:在基于滑模观测器(SMO)的永磁同步电机无位置传感器控制中,位置和转速观测误差较大且抖振较强。为了解决这个问题,在分析传统SMO的基础上,研究一种非奇异快速终端滑模面,并探讨了一种带有积分的滑模控制律,有效地提高了观测精度,且降低了抖振,省去了低通滤波器和转子位置的补偿环节。通过李雅普诺夫函数证明了该观测器的稳定性。最后利用MATLAB/Simulink软件进行仿真。结果表明:所研究的观测器相比传统SMO拥有更好的控制性能。

关 键 词:永磁同步电机    非奇异快速终端滑模    无位置传感器控制

Abstract:In the sensorless control of permanent magnet synchronous motor based on sliding mode observer (SMO), the observation error of position and speed was large and the chattering was strong. In order to solve this problem, the traditional SMO was analyzed. A kind of nonsingular fast terminal sliding mode surface was studied, and a sliding mode control law with integral was discussed, which could effectively improve the observation accuracy, reduce chattering and eliminate the low pass filter and rotor position compensation. The stability of the observer was proved by Lyapunov function. Finally, MATLAB/Simulink software was used for simulation, and the results showed that the control performance of the proposed observer was better than that of the traditional SMO.
Keywords:permanent magnet synchronous motor (PMSM)  nonsingular fast terminal sliding mode  sensorless control
