基于LPV-MPC的风电机组功率-载荷协调控制策略
Coordinated power-load control strategy for wind turbine based on LPV-MPC
摘要
Abstract
Pitch control of large wind turbine is a complex nonlinear control task.How to achieve power regulation and load reduction under system constraints and wind speed disturbance has become a problem.For this problem,a control-oriented linear parameter varying(LPV)model is constructed by using mechanism and parameter identification methods.The gap metric theory is introduced to reduce the complexity of the model,which provides a more accurate linear model for control design.Based on the obtained optimal states,an adaptive model prediction pitch controller(MPC)is proposed with the change of real-time wind speed.The coordinated control of power-load for large wind turbine can be realized under the conditions of system constraints.The simulation examples of OpenFAST show the effectiveness of the proposed model and controller.关键词
