Abstract

The use of position sensors for the variable frequency drive (VFD) has been verified for years. However, more reliable VFDs with smart autonomous systems require side-by-side implementation of sensor and/or sensorless operation. Recently developed active disturbance rejection control (ADRC) provides robustness to VFD uncertainty and its fast response to reject disturbances. Considering the iron loss effect as the disturbance to the permanent magnet brushless dc motor (PMBLDCM) performances, a novel ADRC is proposed in this article. The ADRC current controller considering the iron loss effect is proposed along with an estimation of the back electromagnetic force disturbance used for the position/speed estimation. The proposed controller incorporates a structured inner and outer closed-loop ADRC that considers process delays and extended state observer dynamics. These dual ADRC-based control algorithms are verified for PMBLDCM drive both by simulation study and experimental findings. The improved performance of the proposed method is validated with a laboratory prototype of 2.5 kW PMBLDCM drive system.
