A Nonlinear Modeling Method of Switched Reluctance Motor

Due to difficult establishment of flux linkage model caused by magnetic highly saturation when Switched Reluctance Motor (SRM) operates. A new nonlinear flux linkage model (flux linkage model) for SRM is proposed in this paper. This paper used the Gauss function modeled three special position flux curve, and combined with Fourier series to get other position flux curve, then compared with the measured flux curve to verify the accuracy of the model. The simulation model is set up based on this, and its results verifies the correctness and validity of the nonlinear flux modeling approach, which lays the foundation for the further study of SRM speed regulating system.
