Consequently, the use of advanced control algorithms for active load reductionhas become a relevant part of current wind turbine control systems. In this paper, an individual blade pitch control law isdesigned using multivariable linear parameter-varying control techniques. It reduces the structural loads both on the rotatingand non-rotating parts of the turbine. Classical individual blade pitch control strategies rely on single-control loops withlow bandwidth. The proposed approach makes it possible to use a higher bandwidth since it accounts for coupling at higherfrequencies. A controller is designed for the utility-scale 2.5 MW Liberty research turbine operated by the University ofMinnesota.
