根据级联无刷双馈电机(cascade brushless doubly-fedmachine,CBDFM)转子坐标系下的数学模型,推导得到了它在控制电机同步坐标系下的数学模型,通过对该模型的分析,得出控制电机定子电流的交、直轴分量分别可以实现对电机转矩和控制电机磁链进行有效控制的结论。根据该结论,设计了CBDFM的控制方法,其外环为磁链和转矩环,内环为电流环,实现对控制电机磁链幅值和电机转矩的控制,回避了求解复杂非线性方程的困难,控制算法简单。仿真实验结果证明了该方法的有效性。

By deducing the mathematical model of cascade brushless doubly-fed machine(CBDFM) in rotor coordinate,the model in control machine synchronous coordinate was derived.Based on analysis to this model,it could be concluded that the machine's torque and control machine's flux could be controlled effectively by the cross and direct axis component of the control machine's stator current.According to this conclusion,the CBDFM control method was then designed.With outer-loop as flux and torque loop,inner-loop as current loop,the control of total torque and control machine's flux amplitude was then realized.In the meantime,this control algorithm was simple and avoided solving complex nonlinear equation.At last,simulation results proved the effect of this method.
