    This study introduces an advanced control strategy for doubly fed induction generators (DFIGs) in variable-speed wind energy conversion systems (WECSs), combining model reference adaptive control (MRAC) with input-output linearizing and decoupling control (I/OLDC). The system employs a three-phase, three-level voltage source inverter (3L-VSI) to drive the DFIG, with a focus on regulating active and reactive power through precise rotor current control. The core algorithm leverages feedback linearization to decouple power dynamics, while MRAC enhances tracking accuracy by continuously aligning measured stator power values with their references. Simulation and Hardware-in-the-Loop (HIL) tests using a dSPACE1104 platform and ControlDesk demonstrate superior performance compared with conventional PI control, including rise time < 0.2 ms (MRAC) versus ≈ 4.5 ms (PI), steady-state power errors < 2 % (MRAC) versus ≈ 10 % (PI), active/reactive power decoupling within overshoot of 1.5 % (MRAC) versus ≈ 15 % (PI), stator-current THD of 0.5 % (MRAC) versus ≈ 7 % (PI), and the robustness and reliability of the DFIG-wind system under parameter change and grid-fault of ≈ 50 % (MRAC) versus 20 % (PI). These results confirm that the proposed MRAC–I/OLDC method ensures robust, fast, and accurate power control, maintains grid compliance, and optimizes energy extraction under turbulent wind and grid conditions.
