Fault-tolerant Control of Offshore Wind Turbines With Sea Ice Load Accounting for Actuator Faults
摘要
Abstract
Variable pitch optimization control is a critical method for reducing the impact of sea ice loads on wind turbines.However,frequent adjustments can lead to actuator faults.To minimize the impact of these faults on the turbine's output power,this paper proposes a fault-tolerant control strategy based on switched adaptive sliding mode.Considering the coupling relationship between ice loads,actuator faults,and mechanical characteristics of turbines,a switched linear model is built.Parameters for each operating condition are identified by using test data.Based on the switched linear model,switching sliding mode surfaces,a full-order observer,an adaptive law,and a restrict switch law are designed.A piecewise Lyapunov function is designed by stability theory to prove the convergence of the control system.Relevant gain parameters are solved using the linear matrix inequality method.To prove the effectiveness of the controller,this paper conducts comparative experiments with the optimal gain scheduling control strategy under both healthy and faulty actuator scenarios.The results show that the designed control strategy can quickly respond to system output errors caused by ice loads or faults,rapidly apply compensation commands to the actuators,effectively suppress disturbances of the system,and achieve improved fault-tolerance performance.关键词
