Abstract

Addressing the sensitivity of permanent magnet synchronous motors to external disturbances, a novel sliding mode control (NSMC) strategy is proposed to suppress sliding mode jitter and enhance speed regulation performance. First, an advanced nonsingular fast terminal sliding mode (ANFTSM) surface and a new adaptive power rate reaching law (NAPRRL) were developed. A new switching function replaces the conventional sign function to enhance the system's disturbance immunity and dynamic response speed. Then, the system's anti-interference performance was further enhanced by introducing an improved novel sliding mode observer (INSMO) for feedback compensation of the aggregate disturbance. Finally, MATLAB/Simulink simulations and experimental validations demonstrate that the NSMC control strategy exhibits superior performance in both the start-up response and load disturbance phases, with enhanced dither resistance, rapid dynamic response, and disturbance suppression capabilities.

基于先进达到律的 PMSM 滑动模式扰动补偿速度控制

针对永磁同步电机对外部干扰的敏感性，提出了一种新型滑模控制（NSMC）策略，以抑制滑模抖动并提高调速性能。首先，开发了一种先进的非正弦快速终端滑动模式（ANFTSM）表面和一种新的自适应功率率达到律（NAPRRL）。新的开关函数取代了传统的符号函数，从而提高了系统的抗干扰能力和动态响应速度。然后，通过引入改进的新型滑动模式观测器（INSMO）对总干扰进行反馈补偿，进一步提高了系统的抗干扰性能。最后，MATLAB/Simulink 仿真和实验验证表明，NSMC 控制策略在启动响应和负载干扰阶段都表现出卓越的性能，具有更强的抗抖动能力、快速的动态响应和干扰抑制能力。
