提出了一种基于超扭算法的滑模观测器（STA-SMO）精确转矩闭环控制方法。首先建立了永磁同步电动机的统一数学模型。然后，设计了一个STA-SMO来观测永磁磁链并精确估计转矩。特别是，STASMO成功地消除了滑模的抖振。并对STA-SMO的稳定性进行了详细分析。仿真结果验证了该方法的正确性和有效性。
This paper presents a precise torque closed-loop control method by super-twisting algorithm based sliding mode observer (STA-SMO). A unified mathematical model of permanent magnet synchronous motor (PMSM) is first described. Then, a STA-SMO is designed to observe the PM flux linkage and to estimate the torque precisely. In particular, the STASMO eliminates the chattering of sliding mode successfully. Stability analysis of STA-SMO is also given in detail. Finally, the simulations results demonstrate the accuracy, validity of the proposed method.
