Abstract

Synchronous reluctance machines (SynRMs) have been widely deployed in many industrial regions benefited from its high power density and reliability. However, the performance of SynRMs suffers from the significant torque ripple produced by its special rotor structure. This paper proposes a simplified torque ripple suppression strategy which takes advantage of the torque function concept. Under some reasonable assumptions, the coefficient of torque function is estimated by a tracking differentiator and a Luenberger observer. Then, the compensated d-axis current can be produced by modified torque function for the purpose of reducing the torque ripple. The effectiveness of the proposed method has been proved by several simulation and experimental results.
