| Abstract: | An on-line adaptive efficiency optimization control strategy of permanent magnet synchronous motor (PMSM) drives for electric vehicle (EV) is presented to extend the road haul of EV. The strategy provides a novel adaptive pattern of fast d-axis stator current regulation to find the maximum efficiency operating point of PMSM drives at any operating mode of EV. In order to improve the rapidity of efficiency optimization process, a fuzzy logic control method based on torque compensation and the PMSM mathematic model considering the effects of copper loss and iron loss are adopted, which overcomes the major drawbacks of existing efficiency optimization approach applied to PMSM drives for EV. A 7.5kW PMSM efficiency optimization control system is implemented using a TMS320F240 DSP. Excellent experimental results prove the validity of the proposed strategy. |
