Abstract: In order to solve the problems of strongly nonlinear, multivariable coupling and complexities of the exact analytical model for the switched reluctance motor(SRM), the traditional fuzzy and PI control methods were investigated. After the analysis of system model, the linearly and nonlinearly relationship were established between the plant and controller. A method called hybrid fuzzy PI arithmetic was presented to design a speed controller. A simulation program of switched reluctance drive system (SRD) based on Ansoft and Matlabsimulink was developed. The relationship between behavior of hybrid fuzzy PI controller and SRM performance was studied under different feedback error circumstances. The controller stabilization performance and SRM static/dynamic performance were evaluated at the same time. The physical verification experimental results indicate that both static/dynamic performance and robustness of SRD are improved.
