In a wind turbine's pitch control experiencing high winds, which outcome occurs when the control algorithm oscillates?

💡 Explanation

Resonant structural fatigue emerges because the pitch control system induces oscillations matching the tower's natural frequencies; this triggers a positive feedback loop via the **control loop gain**, therefore increasing stress, rather than stabilizing torque due to constant pitch adjustments.
