Closed-loop Data-Enabled Predictive Control and its equivalence with Closed-loop Subspace Predictive Control

no code implementations22 Feb 2024 Rogier Dinkla, Sebastiaan Mulders, Tom Oomen, Jan-Willem van Wingerden

Factors like improved data availability and increasing system complexity have sparked interest in data-driven predictive control (DDPC) methods like Data-enabled Predictive Control (DeePC).

On the Analysis and Synthesis of Wind Turbine Side-Side Tower Load Control via Demodulation

no code implementations4 Sep 2023 Atindriyo K. Pamososuryo, Sebastiaan P. Mulders, Riccardo Ferrari, Jan-Willem van Wingerden

The high-fidelity OpenFAST wind turbine software evaluates the proposed controller scheme, demonstrating effective reduction of the 1P periodic loading and the tower's natural frequency excitation in the side-side tower motion.

Convex Model Predictive Control for Down-regulation Strategies in Wind Turbines
