Abstract

This paper gives new technique for estimating the rotor position for PMSM drives with higher accuracy and resolution and also controlling of PMSM motor. There are several techniques for doing same. Some of them are average and first order algorithms. Present technique which is used here is vector tracking observer in conjunction with discrete Hall sensors’ output signals, which is similar to a phase-locked loop structure. It consists of a position error detector, based on the vector cross product of the unit back-electromotive-force vectors obtained from a stator electrical model, and a proportional–integral-typed controller to make the position error rapidly converge to zero.This technique does not only compensate the misalignment effect of Hall sensors but also improves their transient operating capability
