Objectives How can we realize a lidar-assisted feedforward controller in the transition region? What are the lessons learned from this field testing campaign? Flatness-based control is an option ... can be combined with baseline feedback control and adaptive lidar data processing. based on inversion of reduced nonlinear model to limit tower motion during transition. tuning necessary with collected turbine and lidar data.
