摘要:

该文从简化的Hayami扩散波方程模型出发,建立了具有瞬时位置和时滞位置线性组合(PDP)的反馈控制模型,讨论了闭环系统解的适定性,然后利用能量范数构造Lyapunov函数,建立了闭环系统的指数稳定性.最后,将控制参数的取值范围与已有文献结果进行对比,得出了该文参数条件更为宽泛的结论,体现了PDP反馈控制器的优越性.

关键词: 扩散波方程, PDP反馈, Lyapunov函数, 指数稳定性

Abstract:

In this paper, a position and delayed position (PDP) feedback controller is established for the Hayami diffusive wave equation. The well-posedness of the closed system is studied firstly, and then, by the method of Lyapunov function, the exponential stability is obtained. Finally, compared with the previous results, the range of the control parameters is expanded in this paper, which shows the efficiency and feasibility of PDP feedback.

Key words: Diffusive wave equation, PDP feedback, Lyapunov function, Exponential stability
