Adaptive Fuzzy Sliding Mode Control for Brushless Doubly Fed Machine

In this paper, because a adaptive fuzzy control is incorporated into the sliding mode control (SMC) to adaptively regulate the adaptive law of SMC, an adaptive fuzzy sliding mode controller (AFSMC) for brushless doubly fed machine (BDFM) adjustable speed system is presented. The proposed controller for BDFM eliminates the average chattering encountered by most SMC schemes, and employs the robustness and excellent static and dynamic performances of SMC. Simulation results show that the proposed control strategy is of the feasibility, correctness and effectiveness.
