| Abstract: | This paper presents a strategy for rotor position and speed estimation at low-speed by establishment of electrical steady-state observer for PMSM.Consequently,starting process of PMSM is accomplished successfully.The back-EMF state observer is designed under high-speed condition,and the rotor speed and position can be estimated by error-tracking controller.This method can achieve effective and stable starting,simple algorithm,small starting current and high reliability.Finally experimental results proved th... |
