The mathematical models of every stage in the vector control are built. A voltage feed-forward method is used to realize the independent control of the current in the MT shaft. On the basis of simplified models, the controlling parameters of the adjuster are gained through engineering design method. A flux observer of six-phase motor is designed based on the flux observer of three-phase electrically excited synchronous motor. According to the advantages and disadvantages of flux observing method, this paper adopts a mixed voltage-current model as the flux observer model. In order to make the vector control method based on non-salient pole synchronous motor fit for salient pole synchronous motor, the equivalent mathematical model of non-salient pole motor is gained after the equivalent substitute of salient pole motor with the theory of two reaction theory of synchronous motor. Simulation research is conducted on the performance of six-phase electrically excited synchronous motor control system based on gap motor flux oriented vector control.
