Fuzzy Logic based Variable-Order Fractional Sliding Mode Control for PMSM
The application of fractional sliding mode control method in permanent magnet synchronous motor (PMSM) has been widely researched, and the order in the control method is constant. In order to further improve the global control performance, a fuzzy logic based variable-order fractional sliding mode control for PMSM was proposed. Based on the mathematical model of the PMSM, the variable-order fractional sliding mode controller ( VOFSMC) was designed firstly and the stability of the proposed method was proved. Then through the performance analysis of fractional sliding mode controller with different order, the optimal variation rules of the order was obtained. At last the fuzzy inference rules were established with error as input and order as output, and the fuzzy logic based variable-order fractional sliding mode controller was designed. The numerical simulation results show that the proposed method has better performance than the conventional constant order fractional sliding control method.
