  • Abstract:This paper focuses on the high frequency current injection method for sensorless control of surface mounted permanent magnet synchronous machines (SPMSM) at low speed. In sensorless control of injection method, a PI close loop is needed to estimate the rotor position. However, constant PI parameters are unable to achieve optimal control effect in both process of dynamic and steady-state. In this paper, fuzzy PI position observer is proposed to realize the real-time parameter adjustment. Simulation and experimental results show that fuzzy PI position observer improves the precision of rotor position estimation and ensures the quickness of the rotor position estimation simultaneously.
