This paper presents a controller for optimizing the crosswind figure-8 motion of a buoyant
airborne wind energy turbine. Crosswind figure-8 motion has the potential to increase …

Motivated by the reduction of overall wind power cost, considerable research effort has been
focused on enhancing both efficiency and reliability of wind turbines. Maximizing wind …

This brief presents a nonmodel-based adaptive control technique that combines principles
from machine learning and iterative design optimization with those of continuous-time …

Wind energy utilization is essential for realizing global energy transformation. To capture
steady and powerful wind resources, wind turbines tend to be more remotely located with …

Estimating the levelized cost of energy (LCOE) of a wind turbine is useful for performing a
cost-benefit analysis of potential designs. The power consumed by blade-pitch actuation is …

Wind turbines are complex dynamic systems forced by stochastic wind disturbances, as well
as gravitational, centrifugal, and gyroscopic loads. Since their aerodynamics are nonlinear …

Variable-speed, horizontal axis wind turbines use blade-pitch control to meet specified
objectives for three regions of operation. This paper provides a guide for controller design …

In this paper we describe an effort recently completed at UT Dallas to develop a high-fidelity
computational fluid dynamics code to test and develop control algorithms aimed at …

With the trend of increasing wind turbine rotor diameters, the mitigation of blade fatigue
loadings is of special interest to extend the turbine lifetime. Fatigue load reductions can be …

The wind farm has an intrinsically distributed structure, where wind turbines are counted as
subsystems of the distributed system. The coupling between the subsystems is the wind flow …
