Robust ADRC Control of a Doubly Fed Induction Generator Based Wind Energy Conversion System

摘要

In this paper the issue of control strategies for the doubly fed induction generator (DFIG) is addressed in a wind energy production. The active and reactive power between the stator of DFIG and the grid are controlled independently by using a novel linear control scheme called the Active Disturbance Rejection Control (ADRC) based on the extended state observer (ESO) in order to ensure the decoupling of the system from the actual disturbance acting on the plant. In order to maximize the power of wind energy conversion, the use of MPPT control is indispensable. Finally, a numerical simulation with MATLAB/Simulink confirms the performance of the proposed controller.
