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。
