Development of a Control-Oriented Model of Floating Wind Turbines

Questo articolo tratta delle sviluppo di un modello di una turbina eolica galleggiante su piattaforma “Tension Leg” e della sintesi di un controllore di velocità delle pale e assetto della piattaforma di tipo H8.

This paper deals with the development of a simplified, control-oriented mathematical model of an offshore variable speed wind turbine with tension leg platform. First, the model is derived with the aim of describing the most relevant physical phenomena of the turbine/platform dynamics, while limiting its complexity. The unknown model parameters are identified and a model validation phase is carried out using FAST, an accurate reference model available in the literature. Then, an H∞ controller is designed for above-rated power operating conditions. The ability of the controller to attenuate the effect of wind variations and waves is tested in simulation both on the small-scale simulation model and on the FAST simulator.
