The Brushless Doubly-Fed Machine Vector Model in the rotor flux oriented reference frame

The paper presents the vector model of the brushless doubly-fed machine (BDFM) in the rotor flux oriented reference frame. The rotor flux oriented reference frame is well known in the standard AC machines analysis and control. Similar benefits can be sought by employing this method for the BDFM. The vector model is implemented in MATLAB/SIMULINK to simulate the BDFM dynamic performance under different operating conditions. The predictions from the vector model are compared to those from the coupled circuit model in simulation. The results are shown for the cascade mode of operation.
