摘要:

该文研究了一类半线性抛物型方程组平衡解的有限维反馈能稳性, 控制器由对应于平衡解的线性化系统的LQ问题所导出. 该文发现在受控系统中如何施加控制是与平衡解有关的, 对于不同的平衡解, 在受控系统中应施加不同的控制.

关键词: 能稳性, 抛物系统, 平衡解, Riccati方程, 反馈控制

Abstract:

In this paper, the author studies internal stabilization of steady-state
solutions to a class of semi-linear parabolic systems including three equations via finite-dimensional feedback controllers. The main idea is to use different internal controllers to stabilize different steady-state solutions. The controllers are provided by considering LQ problems associated with the linearized systems at steady-state solutions, and they are added to one, two or three
equations, depending on the considered steady-state solutions.

Key words: Stabilization, Parabolic system, Steady-state solution, Riccati equation, Feedback controller
