Optimal sliding mode control for doubly fed wind turbines based on an adaptive predefined-time reaching law
摘要
Abstract
To handle the power tracking control problem of doubly fed wind turbines with matched disturbances,the optimal sliding mode control method based on a novel adaptive predefined-time reaching law is proposed in this paper.Firstly,according to the linear optimal feedback control theory,an optimal integral sliding mode surface is designed,which effectively improves the dynamic response characteristics of the closed-loop system during the sliding mode phase.Then,by using the periodicity of a sine function,an adaptive predefined-time reaching law with fewer parameters and simpler structure is designed,which could guarantee the predefined-time arrival to the sliding surface and improve the robustness of the arrival time to initial values.Finally,the proposed methods are extended to the second-order sliding mode case which could eliminate the chattering phenomenon in the controller by integrating the sign function,and the correctness and effectiveness of the proposed results are verified by numerous simulation examples.关键词
