摘要

本文针对永磁同步电机提出了一种非弧形快速终端滑动模态控制（SMC）策略，该策略采用了一种新的片式达到律（PRL），以减少稳态缓冲。设计了速度自适应调节器，使电机在非正常启动或转子锁定时，在直流母线电压条件限制下以最低速度值稳定工作，并引入了干扰观测，进一步提高了控制系统的抗干扰能力。实验测试已经完成。与传统 SMC 的实验结果相比，在 20 rpm、30 rpm 和 40 rpm 的空载条件下，使用带 PRL 的非弧形快速终端 SMC 的控制系统的缓冲抑制率分别降低了 66.7%、57.9% 和 60%。在负载条件下，拟议方法的缓冲抑制和动态稳定时间分别减少了 52.3% 和 53.3%。

Research on Low Speed Operation of PMSM Based on Improved Non-Singular Fast Terminal SMC

A non-singular fast terminal sliding mode control (SMC) strategy with a new piecewise reaching law (PRL) of permanent magnet synchronous motor is presented to reduce the steady-state buffeting in this paper. A speed adaptive regulator is designed to make the motor work stably at the lowest speed value under the limitation of the DC bus voltage condition when the motor starts non-normally or with locked rotor, and a disturbance observation is introduced to further improve the anti-interference ability of the control system. The experiment test is carried out. Compared with the experimental results of traditional SMC, the buffeting suppression of the control system using non-singular fast terminal SMC with PRL is reduced by 66.7%, 57.9% and 60% at 20 rpm, 30 rpm and 40 rpm under no-load condition, respectively. The buffeting suppression and the dynamic stability time of the proposed method are reduced by 52.3% and 53.3% under load condition, respectively.
