The torque ripple in SRM are relatively higher compared to induction machines. In this paper, based on the experimental data of static torque characteristic, a fuzzy-neural network is applied to learning it's inverse model off line, then according to the predefined torque distribute function, optimal current profile is real-time gained by the FNN on line, which results in a linear, decoupled, low ripple control of torque. The performances of the proposed method is demonstrated by computer simulation results.
