H_∞ Based Gain Scheduled Robust Control for Load Mitigation in a Commercial 3 MW Wind Turbine

摘要

The design and analysis of different robust control strategies applied to a commercial 3 MW wind turbine are presented in this paper. An exhaustive simulation analysis is developed with the proposed robust controllers and they are compared to the baseline controller - LTI based - installed in a commercial wind turbine by means of Key Performance Indicators (KPIs). The family of linear models extracted from a high-fidelity aeroelastic code is used to design the robust controllers and this software package is also used to perform a full set of calculations including both extreme and fatigue load cases.
