Experimental study of floating wind turbine control on a TetraSub floater with tower velocity feedback gain

We present an experimental study of floating wind turbine control with inclusion tower motion feedback. The is conducted for a 1:60 scaled-model the DTU 10MW reference on design variant TetraSub floater. A review methods turbines provided, covering both de-tune and feedback methods. next detail implementation in setup that includes real-time integration low-pass filtering measured tower-top acceleration. demonstrate how loop able to stabilize otherwise unstable land-based controller. results further show stability maintained increasing values gain until certain limit. For chosen parameters lab-generated field, which had limited low-frequency energy, we observe variations rotor speed, blade pitch platform are generally larger This finding not generalizable due special inflow conditions because controller optimization performed. controller, substantial response at floater roll frequency identified. caused by influence aerodynamic torque combination constant generator torque. Mitigation through proposed.
