Abstract：Based on the description of brushless doubly fed machine state space model in the rotor reference frame, the brushless doubly fed machine (BDFM) affine nonlinear state space model in arbitrary rotating reference frame is derived by rotating coordinate transformation, and its static DC characteristic is analyzed. On the basis, The decoupling control method of BDFM in the control motor synchronous reference frame is obtained by means of input-output feedback linearization. The necessary condition of the implementation of the presented control strategy is demonstrated. The conversion method and identification method of parameters are also given. Simulation results confirm the effectiveness and the robustness of the proposed strategy.
