Blade pitch control is critical for stabilizing floating offshore wind turbines (FOWTs) in above-rated regions. However, conventional proportional-integral (PI) controllers, typically derived from simplified linear models, often suffer from model mismatch and limited capability in multi-objective optimization. To ove...
Rigid one-mass drivetrain models simplify maximum power point tracking (MPPT) controller synthesis, but their use can create a model-controller mismatch when the implemented wind turbine has a flexible shaft. This study evaluates that mismatch using a nonlinear MATLAB/Simulink model of a 1.5 MW variable-speed horizonta...
Renewable power plants are prone to high-frequency resonances that threaten the stability of their generators. In this regard, the design of supplementary controllers for shaping the output impedance and improving the stability margins is of great interest, although it requires a detailed design procedure. In this work...
Floating offshore wind turbines (FOWTs) face significant challenges in power regulation due to the inherent intermittency and fluctuations of wind resources. To address this issue, this study proposes a novel collective blade pitch controller based on Model Reference Adaptive Control (MRAC) with a constant modificatio...
Abstract. We investigate the stabilization of mathematical models describing the structural dynamics of a monopile wind turbine tower. In the fore-aft plane, we show that the system becomes polynomially stable with an energy decay rate of [Formula: see text] under static output feedback that relies on the velocity and...
