Title: Sliding-mode Control For The Decoupled Power Control Of Doubly-fed Induction Generator

Keywords: Doubly-Fed Induction Generator, flux orientation, power control, sliding mode control, vector control


This paper proposes a decoupled control of active and reactive power for doubly-fed induction generators (DFIG) bu using the rotor current control loop and sliding mode control (SMC). In order to decouple the active and reactive power generated, stator-fluxoriented vector control is applied. The sliding mode control strategy proposes is based on two sliding modes plus PI controllers whose main advantage is the easy implementation. Simulation and experimental results are presented to validate the proposed control scheme for a 2 kW DFIG during stator active and reactive power steps and rotor speed variation. During transient operation it is checked good dynamic response.
