摘要
To model the nonlinear characteristic of the flux linkage for the switched reluctance motor, a modified flux linkage analytical model and a fast model are proposed. The models are based on an original polynomial model which fits the psi-theta curve at different phase currents by analyzing the error percentage curve of the original model in this paper. The coefficient of the polynomial is discussed for a fast model in order to solve the modeling problems quickly. Then, the electromagnetic torque of switched reluctance motor is calculated by the modified model and the fast model, which agree well with the finite element results. Based on the modified model, the simulation model is built in MATLAB/Simulink. Also, an experimental platform is established to validate the proposed models.
