A control system by means of the back electromotive force method is designed for the position-sensorless electric vehicle (EV) after analyzing the principle of position-sensorless control for brushless dc motor. Aiming at the main problems of EV: variation of model and short driving range, a fuzzy sliding-mode controller (FSMC) with regeneration is designed for the EV. The controller uses fuzzy switching gain adjustment to avoid the whippings. The experimental results show that the control system of position-sensorless EV can successfully achieve position-sensorless commutation control and replace Hall sensors. FSMC possesses better performance and higher efficiency than the proportional-integral-differential controller. Additionally, it can recover more energy and increase more driving range.
