Robust LQ Optimal Control for Wind Turbine Power Tracking Operation (2407.20922v1)
Published 30 Jul 2024 in eess.SY and cs.SY
Abstract: In this paper, a robust linear quadratic optimal control approach for accurate active power tracking of wind turbines is presented. For control synthesis, linear matrix inequalities are employed using an augmented wind turbine state model with uncertain parameters. The resulting controller ensures robust stability in different operating regions. In a case study, the novel approach is compared to existing controllers from literature. Simulations indicate that the controller improves power tracking accuracy while leading to similar mechanical wear as existing approaches.
