摘　　要：针对非奇异终端滑模控制方法收敛速度慢等缺点,本文提出一种基于改进非奇异终端滑模的无位置传感器控制方法。以基于九开关变换器的对称六相PMSM为研究对象,设计了无位置传感器控制方法,进行了稳定性分析。仿真结果结果表明,相比于非奇异终端滑模,改进非奇异终端滑模控制方法能够有效提高观测系统收敛速度,减小抖振。Aiming at the shortcomings of non-singular terminal sliding mode control method,such as slow convergence speed,a position sensorless control method based on improved non-singular terminal sliding mode was proposed.A position sensorless control method was designed for symmetrical six-phase PMSM based on nine-switch converter.The stability analysis was proposed.Simulation results show that compared with non-singular terminal sliding mode,improved non-singular terminal sliding mode control method can effectively improve observing system convergence speed,reduce chattering.
