Résumé en anglais

This paper shows a strategy to design a multivariable and multi-objective controller based on the H∞ norm reduction applied to a non-linear wind turbine. The wind turbine model has been developed in GH Bladed and it is based on a 5 MW wind turbine defined in the Upwind European project. The designed controller works in the above rated power production zone and carries out generator speed control and load reduction on the drive train and tower. In order to do this, two robust H∞ MISO (Multivariable Input Simple Output) controllers have been developed. These controllers generate pitch and torque set-point values to achieve the imposed control objectives. The linear models obtained in GH Bladed and the correctly defined weight functions are used to make the controller synthesis, where some notch filters are included in the controller dynamics. The obtained controllers are validated in GH Bladed and an exhaustive analysis is done to calculate the load reduction rate in wind turbine components.< Réduire
