Implementation of an Improved Motor Control for Electric Vehicles

Electric vehicles are regarded as a significant way to mitigate the global energy crisis and environmental pollution problem. Motor control is very important part for electric vehicles. As hardware, motor controller usually has components such power module, microprocessor unit, IGBT driver, sensors, resolver-to-digital convertor. software, field-oriented (FOC) with space vector pulse width modulation (SVPWM) popular method, while model predictive (MPC) recently shown great potential in drives. In this paper, both FOC MPC discussed performances compared based on experiments. implementation digital processor, discretization normalization addressed, flux observer speed estimation discussed. Some practical issues also talked about, field weakening control, overmodulation, etc. This paper focuses how implement improved industrial applications. The steady-state torque of verified by test-bench shows good performance these
