Abstract
Official abstract text for this publication.
A control system for a floating offshore wind turbine (FOWT). The FOWT includes a floating base, a tower, a nacelle, and rotor with blades that harvest energy from wind passing the FOWT. Without a rigid support, however, the FOWT is able to move. The controller uses generator speed and platform pitch position of the FOWT as inputs and manipulates blade pitch and torque resistance to achieve stability.
First claim
Opening claim text (preview).
We claim: 1 . A controller for a floating offshore wind turbine (FOWT) comprising: a blade pitch actuator configured to adjust a blade pitch of blades of the FOWT; a torque resistance actuator configured to adjust torque resistance of the FOWT; a processor; and a memory configured to store instructions that, when executed by the processor, cause the controller to perform a method, the method comprising: receiving a generator speed and a platform pitch angle as an input to the controller; and based, at least in part, upon the input to the controller, adjusting at least one of the blade pitch angle using the blade pitch actuator and the torque resistance using the torque resistance actuator to improve stability of the FOWT, wherein a gain scheduler is derived using a multi-input, multi-output (MIMO) system for robustness; and wherein the controller executes a combined gain-scheduled proportional-integral (PI) control and platform feedback (PF) control. 2 . A controller for a floating offshore wind turbine (FOWT) comprising: a blade pitch actuator configured to adjust a blade pitch of blades of the FOWT; a torque resistance actuator configured to adjust torque resistance of the FOWT; a processor; and a memory configured to store instructions that, when executed by the processor, cause the controller to perform a method, the method comprising: receiving a generator speed and a platform pitch angle as an input to the controller; and based, at least in part, upon the input to the controller, adjusting at least one of the blade pitch angle using the blade pitch actuator and the torque resistance using the torque resistance actuator to improve stability of the FOWT, wherein a gain scheduler is derived using a multi-input, multi-output (MIMO) system for robustness; and wherein the controller executes a single-input, single output (SISO) proportional-integral control loop and a set of multi-input, multi-output control loops. 3 . A controller for a floating offshore wind turbine (FOWT) comprising: a blade pitch actuator configured to adjust a blade pitch of blades of the FOWT; a torque resistance actuator configured to adjust torque resistance of the FOWT; a processor; and a memory configured to store instructions that, when executed by the processor, cause the controller to perform a method, the method comprising: receiving a generator speed and a platform pitch angle as an input to the controller; and based, at least in part, upon the input to the controller, adjusting at least one of the blade pitch angle using the blade pitch actuator and the torque resistance using the torque resistance actuator to improve stability of the FOWT, wherein a gain scheduler is derived using a multi-input, multi-output (MIMO) system for robustness; and wherein the controller executes a combined gain-scheduled proportional-integral (PI) control and platform feedback (PF) control; and wherein the controller executes a single-input, single output (SISO) proportional-integral control loop and a set of multi-input, multi-output control loops.
