摘要

研究了Hilbert空间中一类演化方程的反馈镇定问题。利用Lyapunov函数方法，给出了闭环系统全局一致实际收敛的充分条件。基于全局零可控性，构造了一个保证不确定系统全局一致实用稳定的输出反馈控制器。最后给出了一个数值应用，说明了理论结果的适用性。

On the asymptotic stabilization of the non-autonomous evolution equations in Hilbert spaces

This paper deals with the practical feedback stabilization of a class of evolution equations in Hilbert spaces. By using the Lyapunov function method, we give sufficient conditions for the global uniform practical convergence of the closed-loop system. Based on the global null-controllability, we construct an output feedback controller that guarantees global uniform practical stability of uncertain systems. A numerical application is given to show the applicability of our theoretical results.
