Proposal
The sustainability of transportation is one of the most pressing issues of the twenty-first century. As carbon emissions from vehicles fitted with internal combustion engines continue to accumulate in the earth’s atmosphere, electric vehicles have become an attractive alternative for daily transportation. Battery powered permanent magnet synchronous motors (PMSM) have become the standard in electric vehicles due to their high power density, high efficiency, and light weight. With the current state of battery technology, the range of electric vehicles is limited. As consumers demand electric vehicles with similar range capabilities to conventional vehicles, the efficiency of electric motor control has become an important topic of research. Presented is a new method of PMSM control achieved through the modeling of several parameter variations in the motor. Accurate models of the parameters being considered are derived and utilized to maximize the efficiency of the developed control method. After significant efficiency testing and analysis, the proposed control method achieves noticeably better efficiency than the standard maximum torque per ampere (MTPA) method as more controllable losses are being considered. This method can be implemented on any PMSM in an electric vehicle improving efficiencies and subsequently range. This will help facilitate a universal switch to electrified transportation resulting in air quality improvements across the Earth.
