Characteristic Simulation of Adjusting Speed System With Doubly-Fed Brushless Machine

After introducing simply the structure and operation theory of doubly-fed brushless machine (DFBM), the coupling parameters between main winding and auxiliary winding are analyzed. The mathematics model of the DFBM is derived and constant power angle control strategy in the real coordinate is also put forward in this paper. Based on SIMULINK technology, the common simulation module of DFBM has been built. The correctness and credibility of mathematics model and common simulation module have been proved by the consistency of the simulation and experimental results
