摘要：
With regard to the position sensorless control at whole speed range for interior permanent magnet synchronous machine (IPMSM) drives, existing speed or position combination based hybrid control methods suffer from the implementation problem due to high computational complexity. This paper presented a single Luenberger position observer based hybrid control method using normalized position error signal combination. The square-wave voltage injection and the back electromotive force (EMF) model based methods were adopted to extract the normalized position error information at low- (zero-) and middle- to high-speed range respectively. And the normalized position error information was combined through the speed dependent weighted function. The single Luenberger position observer was utilized to estimate the rotor position and speed. The proposed hybrid control method can guarantee the position sensorless control at whole speed range with low computational complexity and easy-to-implement structure. Experiments on a 2.2kW IPMSM sensorless vector controlled drive have been carried out to verify the effectiveness and practicability of the proposed scheme. © 2017 Chin. Soc. for Elec. Eng.
