| Abstract |
This paper proposes a torque ripple reduction method with minimum current RMS value for switched reluctance motors (SRM). In the proposed method, the current waveform to achieve constant torque is derived based on a mathematical model of magnetization characteristics. In particular, the current waveform is optimized in term of the reduction of the current RMS value and the satisfaction of the input voltage limitation. The algorithm for determining the torque command is introduced to derive current command which is possible to generate by the input voltage and lead to the design of the maximum torque per current RMS value without any complex and time-consuming computation process. A three-phase 18S/12P type SRM is used in simulation and experiment in order to validate the proposed method. As a result, the reduction of torque ripple by 65.8\% and the reduction of the current RMS value by 19.2\% are achieved by proposed method. |
