Abstract：Position sensor fault is one of the important reasons to reduce the reliability of interior permanent magnet synchronous motor (IPMSM).For avoiding lag angle observation and chattering defects of sliding mode observer insensorless algorithm, this paper proposed a sensorless control of IPMSM based on active disturbance rejection controller (ADRC). An ADRC is designed to control internal current loops of IPMSM in extended electromotive force frame, so that it is no longer dependent on permanent magnet flux parameters. For positon and speed estimation, the extended electromotive force is regarded as an unknown disturbance and estimated by an extended state observer. And then, the speed and rotor position are generated by the phase lock loop.Finally,simulation and experimental results demonstrate that the proposed control strategy can not only accurately estimate the rotor position of the IPMSM, but also have a good performance in the steady state.
