Abstract：The maximun torque per ampere control can take use of the relactance torque of interior permanent magnet scychronous motor. But the lots of computation is brought by this control strategy. So it is not realized easily. In this paper, the iterative method is used to getting the curve of relationship between the electromagnetic torque and the current component. Then three 2-functions are applicated to analoging the relationship curve.Insteading of discrete spots of traditional method of look up table, these approximate curves which are obtained by above threes 2-functions are employed into MTPA. Then the dynamic performance of the system can be enhanced.At last, the dynamic performance of the two method are compared by simulation and experiment. The results approv the effectiveness and advantage of this proposed strategy.
