要約(英語): This paper proposes a method for torque ripple estimation and reduction of interior permanent magnet synchronous motors (IPMSMs) with concentrated winding considering the nonlinearity of magnetization characteristics. First, the proposed torque ripple estimation method, which ignores nonlinearities such as magnetic saturation and cross-coupling, is derived and some problems of this approach are presented. Then, another method that considers the nonlinearity of the magnetization characteristics is proposed, which is based on simple approximations of the magnetization curve. After that, a method for torque ripple reduction is proposed, which is based on the adaptive identification of the equivalent torque coefficient. Finally, the performance of the proposed method is experimentally evaluated to demonstrate the feasibility of the proposed method.
