Description
Summary:[Display omitted] ► Rotor current is controlled. ► FuzzyMIT, AnfisMIT is introduced in the Improved Adaptive Internal Model Controller. ► Fixed and variable gain Adjustment Mechanisms are compared. ► The influence of variable gain Adjustment Mechanism is simulated. ► The performance is improved using single pulse dither signal. This paper presents the effect of a single pulse dither signal injection in adaptive internal model controller for a doubly fed induction generator (DFIG)-based wind farm. Rotor current controller using adaptive internal model controller is designed with different Adjustment Mechanisms like Lyapunov theory, fuzzy and ANFIS to improve the voltage sag ride through. During voltage sag period the dither signal is injected in the controller to improve the performance of the controller. Simulation results are presented to demonstrate the proposed control strategy during variations in fixed and variable gain Adjustment Mechanism.
