A novel IPMSM model for robust position sensorless control to magnetic saturation

This paper presents a novel interior permanent synchronous motors (IPMSMs) model for position sensorless control. The proposed model has robustness with respect to magnetic saturation. Furthermore, this model can approximately estimate the maximum torque control (MTC) frame, which is possible to realize simple and robust sensorless control system. In addition, the sensitivity of inductance parameters in this model has also been discussed. Moreover, a position sensorless control system based on this model has been shown.
