摘要
Torque-ripples in a permanent magnet synchronous motor (PMSM) deteriorate control precision. This paper presents a method of attenuating such a kind of a torque-ripple based on the combination of the equivalent-input-disturbance (EID) and the sliding-mode control (SMC). While a low gain of an SMC system avoids chattering phenomenon, the robustness of the system is not satisfied. The EID estimator is incorporated in the system to solve this problem. The effectiveness of the combination of the EID approach and the SMC has been verified by simulations. A comparison with the conventional SMC method demonstrates the priority of the presented method.
