Efficient Velocity-Based Quasi-Linear Model Predictive Control for Wind Turbine Side-Side Tower Periodic Load Reductions

Research output: Contribution to journalArticleScientificpeer-review

Abstract

Advancements in wind turbine technology have made wind energy more cost-competitive. While taller towers use less material, they are more susceptible to fatigue. This study introduces a convex model predictive control scheme to actively counteract side-side periodic loads using a velocity-based approach, which captures the system's nonlinear behavior without requiring extensive prior operating points. A quasi-linear parameter-varying dynamic model for wind turbine towers is established through model demodulation transformation. Simulation results show a 96% reduction in net force in the side-side direction at the tower top under turbulent wind conditions.
