چکیده انگلیسی


• We design a pitch controller considering a turbine linearized at yawed inflow.
• We evaluate the control performance at wide range of turbulent wind conditions.
• The controller gives at least 31.54% reduction in blade out-of-plane fatigue load.
• The controller gives at least 35.32% reduction in the tower fore-aft fatigue load.
• It gives at least 29.80% reduction in the tower side-to-side fatigue load.

Recent developments in sensor and actuator technologies have promoted the design and implementation of individual pitch controllers (IPCs) to mitigate fatigue loads on turbine blades caused by vertical wind shear. So far, IPCs have been designed assuming perpendicularity of the oncoming wind with respect to the turbine rotor plane as an independent yaw controller is dedicated to eliminate any misalignments. In this paper, a multi-input-multi-output (MIMO) IPC is designed based on the knowledge of mitigated blade load at a yawed inflow condition (i.e., yaw misalignment at certain angular position). Nonetheless, the proposed IPC is still to operate in the typical turbine configuration, in which the turbine is aligned with the wind direction. Performance of the proposed IPC is compared with that of the baseline collective pitch controller (CPC) and baseline IPC on simulations of the NREL 5 MW reference turbine at various turbulent wind conditions. Compared with the baseline CPC, the proposed controller is shown to contribute at least a 31.54% reduction in the blade out-of-plane fatigue load, a 35.32% reduction in the tower fore-aft fatigue load, and a 29.80% reduction in the tower side-to-side fatigue load.
