| Abstract |
Filtering method exerts direct effects on extracting high frequency current signal in carrier injection based sensorless control for IPMSM drives, and further affects the position estimation accuracy. A wavelet based filtering approach superior to conventional Butterworth band-pass filter is proposed and verified on a 2.2-kW IPMSM sensorless drives. |
