Dynamic Modeling and Simulation of a Flexible Wind Turbine for a Multi-objectives Control

In This paper we provide a model of flexible Wind turbine for multi-objectives control objectives, such load mitigation, speed regulation, power maximization and vibration control, with minimum number of states, needed to design control system. We use Lagrange method to develop the dynamics model; it includes the flexibility of the blades and tower, torsion and rotational dynamic of the shaft. This model describes the dynamic behavior and vibrations due to deformations of the different parts of wind turbine and generator speed. It subdivide to several sub-models such aerodynamic model, structural model and actuator pitch angle model witch are interconnected between
