- Abstract:
- In view of the high salient pole rate structural features and wide range operation characteristics ofpermanent magnet synchronous motor ( PMSM) used in electric vehicles.maximum torque per ampere (MT-PA ) vector control strategy of PMSM based on variable model was studied in this paper. For higher controlprecision.rotor flux linkage components along with inductance and rotor flux linkage value in the differentloads were first obtained with spectrum analysis and frozen permeability methods.the accurate motor modelwas developed,and the corresponding MTPA current vector expressions were derived. Furthermore,its controlcharacteristics were studied.and some comparisons about control characteristic among MTPA based on variableparameters model, fixed parameter model and control characteristic were made.The results show that the MT-PA based on variable parameters model can find more higher current utilization compared withid control andcan get better dynamic performance compared with itself based on fixed parameter model.
