- Additional information
- Large wind turbines have significant unbalanced rotor loading and tower bending at high wind speed, leading to enhanced structural fatigue and shortened blade life. Individual pitch control (IPC) can balance this asymmetry, but pitch actuator faults cause further imbalance. In this novel analysis, an NREL 5MW aeroelastic model is used to show how to compensate for pitch actuation faults, restore rotor symmetry and mitigate against tower bending, using robust fault estimation and fault-tolerant control (FTC).
