摘要
该文首先给出控制电机电流源供电时无刷双馈电机在转子坐标系下的状态空间模型,经旋转坐标变换得到控制电机同步坐标系下的仿射非线性状态空间模型,分析其静态直流特性。以此为基础应用反馈线性化方法解决无刷双馈电机的解耦控制问题,得到控制电机同步坐标系下的解耦控制方法及其实现的必要条件,给出相关参数的折算方法和测试方法。仿真结果证明该文给出的控制方案的有效性和鲁棒性。
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 als o given. Simulation results confirm the effectiveness and the robustness of the proposed strategy.
