【Abstract】 With the advantages of variable speed and constant frequency,brushless doubly-fed machine(BDFM)has broad application prospects in Marine shaft power,hydropower and wind power system. However,there is no mature control method with high performance at present.For the practical application of BDFM(brushless doubly-fed motor)on VSCF generator model,this paper put forward a kind of flux observation method based on PR controller.It′s the foundation for realizing brushless doubly-fed generator vector control algorithm.Contrasting with pure integration method and using the simulation,this paper verified the correctness and practicability for this method on flux observation.更多还原
