Terminal sliding mode speed controller based on vector control for brushless doubly fed machine

In this paper, based on the principle of rotor field oriented vector control (VC), a terminal sliding mode controller (TSMC) for brushless doubly fed machine (BDFM) adjustable speed system is presented. Because of using the fast terminal sliding mode control, the proposed controller for BDFM eliminates the average chattering encountered by most TSMC schemes, and employs the robustness and excellent dynamic performances of TSMC. Simulation results show that the proposed control strategy is of the feasibility, correctness and effectiveness. © 2011 IEEE
