Reduction Method of Current RMS Value, DC Current Ripple, and Radial Force Ripple for SRM based on Mathematical Model of Magnetization Characteristic
This paper proposes a motor current RMS value, DC current ripple, and radial force ripple reduction method under zero torque ripple for switched reluctance motor (SRM). In the proposed method, the current waveform to achieve constant torque is derived based on a mathematical model of magnetization characteristic. In order to optimize multiple objective functions considering a trade-off relationship, the weight function is introduced. In particular, quantitative evaluation functions are derived from the mathematical model for avoidance of time-consuming numerical process. In the proposed method, it is possible to derive the desired current waveform for the motor current RMS value, the DC current ripple, and the radial force ripple by setting appropriate weights. The reduction of the motor current RMS value, DC current ripple, and radial force ripple by 18%, 45%, and 37%, respectively, are confirmed.
