摘　　要：设计了一个双复合滑模面滑模观测器在线辨识异步电机转子电阻,用于提高异步电机间接磁场定向矢量控制性能。尽管观测器是在静止坐标系下实现的,但其推理和设计过程是在转子磁场定向同步旋转坐标系下完成的。这种处理方法,使得静止坐标系下复合滑模面的本质得以清晰揭示,使得单个复合滑模面滑模观测器的不足得以暴露,使得双复合滑模面滑模观测器的提出得以自然呈现,从而完善了复合滑模面滑模观测器设计的理论基础。相关仿真和实验结果验证了该文的推理,展示了该文设计的双复合滑模面滑模观测器的收敛性、观测精度、参数鲁棒性以及动态性能。This paper proposes a double compound manifold sliding mode observer （SMO） used to update the rotor resistance of induction motor online, with the aim to improve the performance of the indirect field oriented vector control. The observer is implemented in the stationary reference frame, though it is analyzed and designed in the rotor field oriented synchronous reference frame. By this means, the essence of the compound manifold is feasible to be revealed clearly, the shortcoming of the single compound manifold SMO is feasible to be exposed, the new double compound manifold SMO is feasible to be derived out naturally, and all of these finally contribute to the theory for the compound manifold SMO. Through simulation and experimental results, the analysis is validated, and the convergence, accuracy, parameter robustness, and dynamic performance of the designed double compound manifold SMO are demonstrated.
