英文摘要：

A noble method was proposed in this paper which can estimate the location of rotor by improving Bloomberg observer.In this ease the high frequency rotating voltage injection method was adopted to estimate the location of rotor.Meanwhile,the theory of high frequency rotating voltage injection method was introduced and the mathematical model was built.A Butterworth filter and Bloomberg observer was designed,then the algorithm was implemented on XMC4500.The method was proved correct and efficient by experiments and simulations.
