摘要 研究一种带无速度传感器的永磁同步电机PMSM(permanent magnet synchronous motor)反步终端滑模控制策略。为了解决硬传感器可靠性差的问题,设计新型无速度传感器取代硬传感器,能够有效地估计电机的实时转速,提高系统的稳定性。分析反步控制与终端滑模控制的特点,研究一种基于终端滑模负载观测器的反步控制方法,有效地提高系统的的响应速度,增强系统的鲁棒性。并利用李雅普诺夫理论证明系统的稳定性。仿真及实验表明系统具有良好动态性能。 We studied a PMSM backstepping sliding mode control strategy with speed sensorless.In order to solve the problem of poor reliability of hard sensors,a new type of speed sensorless was designed to replace the hard sensor,which could effectively estimate the real-time speed of the motor and improve the stability of the system.We analyzed the characteristics of the backstepping control and terminal sliding mode control.We studied a backstepping control method based on the terminal sliding mode load observer,which could effectively improve the response speed of the system and enhance the robustness of the system.The stability of the system was proved by Lyapunov theory.Simulation and experimental results show that the system has good dynamic performance.
