摘　　要：针对永磁同步电机传统滑模控制存在收敛速度慢、抖振大和对不匹配扰动敏感等问题,提出一种新型控制策略。首先,设计了一种新型非奇异快速终端滑模控制,利用积分项减小系统稳态误差;其次,提出了一种新型趋近律,引入切换函数改进系统趋近速度,并应用于矢量控制系统速度控制器中;再次,设计扩张观测器对扰动进行观测,并前馈补偿至速度环中;最后,对该控制策略进行仿真分析。结果表明,与传统滑模控制相比,所提新型控制策略能够有效提升系统收敛速度、降低系统抖振和抑制不匹配扰动,为永磁同步电机控制系统设计提供一种新的思路。Aiming at the problems of slow convergence speed,large chattering and sensitivity to mismatched disturbance in traditional sliding mode control(SMC)of permanent magnet synchronous motor(PMSM),this paper proposes a new control strategy.Firstly,a new non-singular fast terminal sliding mode control(NFTSMC)is designed to reduce the system's steady-state error by using the integral term.Secondly,a new reaching rate is proposed,and a switching function is introduced to improve the reaching speed of the system,which is applied to the speed controller of the vector control system.Thirdly,an extended state observer(ESO)is designed to observe the disturbance and provide feedforward compensation to the speed loop.Finally,the control strategy is simulated and analyzed.The results show that the proposed new control strategy can effectively improve the system's convergence speed,reduce chattering,and suppress mismatched disturbance compared with traditional sliding mode control,providing a new idea for the design of permanent magnet synchronous motor control systems.
