The IPC is a technique used for reducing structural loads in wind turbines like wind shear, tower shadow and wind turbulence by means of a control loop whose outputs are the resulting Tilt and Yaw Moments and the manipulated variables are the blade pitch angles. As the wind turbine model for structural analysis is highly nonlinear, with parametric uncertainties and variations, this paper proposes an IPC-based decentralized Robust Model Reference Adaptive Controller, RMRAC, aiming to address these challenges. The proposed IPC-RMRAC makes use of strain gauges to measure the blade root loads and controls each blade pitch angle independently. Simulations with 1.5 MW wind turbine using NREL FAST software were performed, showing the feasibility of the proposed algorithm. The results are discussed and compared with Collective Pitch Controller.
