A new control strategy based on adaptive second order sliding mode approach is applied to a floating wind turbine system in the above rated region. This adaptive controller is well adapted to a highly nonlinear system as floating wind turbine, and can be easily implemented with very reduced knowledge of modeling. The proposed controller partially based on multi-blade coordinates transformation combines collective and individual collective blade pitch control, for power regulation, platform pitch motion reduction and reduction of blades fatigue load. The proposed controller is implemented on FAST simulator and shows high level of performances.

基于自适应二阶滑模的浮式风力发电机单叶片/总叶片桨距控制

基于自适应二阶滑模方法的一种新的控制策略被应用于上述额定范围内的浮动风力涡轮机系统。这种自适应控制器非常适合于高度非线性的系统（如浮动风力涡轮机），并且只需很少的建模知识就可以轻松实现。所提出的控制器部分基于多叶片坐标变换，结合了集体和个体集体叶片变桨控制，以进行功率调节，平台变桨运动降低和叶片疲劳载荷的降低。所提出的控制器在FAST模拟器上实现，并显示出很高的性能。
