Model predictive control (MPC) is receiving attention in wind turbine controller design due to its ability to explicitly handle state and input constraints. Robust model predictive control (RMPC) additionally accounts for uncertainty in the future evolution of the system. Here, RMPC is compared with nominal MPC for the purposes of fore-aft tower damping of large wind turbines. The two controllers...
Wind loads on buildings in realistic environments may be considerably different from those measured on isolated buildings. Neighboring structures may either decrease or increase the flow-induced forces on the building being considered. In this paper a rigid model wind tunnel test under conventional terrain C wind field was performed to the 1:250 reduced-scale model of a high-rise building with three...
The dynamic characteristics of wind turbine generator tower are studied using the aerodynamics and structural dynamics theories, the mathematical model and the structure model of the tower are established. The numerical simulation method is used to simulate the turbulence flow of the wind, the turbulence model is customed in ANSYS. The 32 bands frequency and vibration mode are analyzed and the wind...
