Abstract

This paper presents a novel robust stator voltage oriented rotor current controller structure for grid connected doubly fed induction generators (DFIG). Controller is based on a proportional controller with first order low pass filter disturbance observer which estimates machine parameter dependent nonlinear terms. Therefore, necessity of accurate knowledge of machine parameters is not required. The results are demonstrated in experimental laboratory setup.
