TL;DR: In this work, a ℋ∞ controller design approach for lidar-based closed-loop wake redirection is investigated and a single controller is designed using models that are obtained from the wind farm simulation tool WFSim.

TL;DR: This paper designs two alternative dampers for the lightly damped drivetrain and tower modes of an experimental turbine and demonstrates that even in this sub-problem of wind turbine control consisting of only two loops, the use of advanced design and validation techniques is very effective at convergence quickly to good control designs and quickly assessing their performance.

TL;DR: In this paper , three active power control strategies pushing this shift of paradigm are investigated, namely: wake-loss compensation, thrust balancing, and load-limiting control, and the findings of large eddy simulations of a reference wind farm show that wake loss compensation indeed improves the power generation on waked wind farms, but at the price of increased structural loads on certain turbines.

TL;DR: In this paper, a closed-loop, economic model-predictive control approach for wind farms is presented, which is constructed from first principles using open-source tools to be suitable for adjoint-based optimisation of turbine yaw angles.
