The rotor position PLL is parameter variation insensitive, requiring only an estimate of the magnetization inductance for it to operate. It is also insensitive to noise in the electrical measurements. Proof of concept is by: (1) digital simulations and (2) experimental testing of a laboratory prototype.enasynchronous generatorsmagnetisationphase locked loopsrotorsturbogeneratorswind power plantswind turbinesSensorless Maximum Power Point Tracking of Wind by DFIG Using Rotor Position Phase Lock Loop (PLL)Journal Article10.1109/TPEL.2008.2009938
