Model-based design of a wave-feedforward control strategy in floating wind turbines

Abstract. Floating wind turbines rely on feedback-only control strategies to mitigate the negative effects of wave excitation. Improved power generation and lower fatigue loads can be achieved by including information about incoming waves in turbine controller. In this paper, a wave-feedforward strategy is developed implemented 10 MW floating turbine. A linear model established utilized understand how excitation affects rotor speed so power, as well show that collective pitch suitable for reducing feedforward controller designed based inversion model, gain-scheduling algorithm proposed adapt action changes. The performance novel examined first means analysis then with non-linear time-domain simulations FAST. This paper proves some play crucial role improving quality life. particular, achieves goal complementing industry-standard feedback Together strategy, provides insights response collective-pitch waves, which could useful future control-design studies.
