This paper studies the mathematical model considering iron loss in the d-q axis of six phase permanent magnetic synchronous motor (PMSM), through the expansion of Field-Oriented Control (FOC) based on three phase PMSM, the simulation model of six phase PMSM under environment of simulink7.0 is set up, which has fast dynamic response, high steady-state precision, and has no problems about current balance compared to dual three phase PMSM. In order to get an accurate simulation results, this mathematical model takes iron loss into account. The simulation results show that iron loss have bad effects on the performance of PMSM especially affect the dynamic response, and to reduce the bad effects, the resistance of the motor core should be increased.

Based on the mathematical model analysis of the three-phase voltage source PWM rectifier under abc reference frame and dq reference frame in this paper, a kind of three-phase voltage source PWM rectifier feed-forward decoupling control strategy is proposed. Dynamic response of DC bus voltage for PWM rectifier is very important, because higher response means little DC bus capacitor. An adaptive PI controller for the DC bus voltage was designed in this paper in order to improve the dynamic response. The experimental results indicate that this control method has good steady-state performance and fast dynamic response. For the reason of its simple, this control method has certain practical value.
