IPMSM sensorless control based on fuzzy active-disturbance rejection controller for electric vehicle

Abstract

In the interior permanent magnet synchronous motor (IPMSM) sensorless control system for electric vehicle (EV), in order to improve system robustness and adaptive ability, a novel active-disturbance rejection controller (ADRC) is presented in this paper. In practice, the ADRC parameters are difficult to operate and adjust, so we introduce the fuzzy control, combined with their own characteristics, a self-adapted active disturbance rejection controller with fuzzy control theory is designed. Considering the inner and outer disturbance of the system as the unknown disturbance, and the sensorless control of IPMSM is got by means of the novel ADRC. Simulation results show that the system has strong adaptive ability of disturbance and robust in different speed range, and it has high accurate speed estimation. Feasibility and advantages of the control strategy has been validated in the field of electric vehicle control.
