This special issue comes from a real need to have an overview about the challenges of modelling and control for Wind Turbine (WT) systems, which require reliability, availability, maintainability, and safety over power conversion effi-ciency. These topics have begun to stimulate research and development in the wide control community particularly for these installations that need a high degree of tolerance with respect to possible fault. Note that this topic repre-sents a key point mainly for offshore wind turbines with very large rotors, since they are characterized by challenging modeling and control problems, as well as expensive and safety critical maintenance works. In this case, a clear con-flict exists between ensuring a high degree of availability and reducing maintenance times, which affect the final ener-gy cost. On the other hand, wind turbines have highly nonlinear dynamics, with a stochastic and uncontrollable driv-ing force as input in the form of wind speed and self induced loads, thus representing an interesting challenge also from the modelling point of view. Fault tolerant control methods can provide a sustainable optimization of the energy conversion efficiency over wider than normally expected working conditions. This special issue is devoted to any kind of fault detection and isolation (FDI) and fault tolerant control methods ap-plied to WT systems. The goal of this issue is to provide a state of art picture of model-based as well as data-driven methods that take into account realistic conditions such as in the presence of unknown uncontrollable inputs, struc-tured and unstructured model uncertainties.

Abstract
This special issue comes from a real need to have an overview about the challenges of modelling and control for Wind Turbine (WT) systems, which require reliability, availability, maintainability, and safety over power conversion effi-ciency. These topics have begun to stimulate research and development in the wide control community particularly for these installations that need a high degree of tolerance with respect to possible fault. Note that this topic repre-sents a key point mainly for offshore wind turbines with very large rotors, since they are characterized by challenging modeling and control problems, as well as expensive and safety critical maintenance works. In this case, a clear con-flict exists between ensuring a high degree of availability and reducing maintenance times, which affect the final ener-gy cost. On the other hand, wind turbines have highly nonlinear dynamics, with a stochastic and uncontrollable driv-ing force as input in the form of wind speed and self induced loads, thus representing an interesting challenge also from the modelling point of view. Fault tolerant control methods can provide a sustainable optimization of the energy conversion efficiency over wider than normally expected working conditions. This special issue is devoted to any kind of fault detection and isolation (FDI) and fault tolerant control methods ap-plied to WT systems. The goal of this issue is to provide a state of art picture of model-based as well as data-driven methods that take into account realistic conditions such as in the presence of unknown uncontrollable inputs, struc-tured and unstructured model uncertainties.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
