Estimation of Permanent Magnet Synchronous Motor Rotor Position for Electric Vehicle Based on Improved Sliding Mode Observer
摘要
Abstract
Permanent magnet synchronous motor(PMSM) as a driving motor directly affects the performance of electric vehicles.With account of advantages compared to traditional position sensors,sensorless detection of rotor position technology has became an important research direction.After considering the traditional sliding mode observer control principle,a modified sliding mode observer was proposed,which employed sigmoid function instead of saturation function to further improve the detection accuracy and continuity of a rotor and better weakened the "chattering".The mathematical model and Simulink simulation were established for the control system of PMSM sensorless detection based on a novel sliding mode observer.Compared with the common methods,the advantages of the new type of sliding mode observer were more intuitive,and the feasibility of the new control system was verified.关键词
