This paper proposes a dynamic output feedback decentralized pitch controller for flexible wind turbines. Both collective and cyclic (individual) pitch controllers are considered. The collective pitch controller aims at improving the rotor speed regulation and maximizing the harvested electrical power, without violating the pitch actuator limits. On the other hand, the cyclic (individual) pitch controller...
This paper proposes a design of sophisticated multi-Objective H2/H∞ collective pitch controllers using linear Matrix Inequalities' techniques. The proposed controller's design takes into account model uncertainties by designing a controller based on a polytopic model. The LMI-based approach allows additional constraints to be included in the design (e.g. H∞ problem, H2 problem, H∞/H2 trade-off criteria,...
