一类不确定热方程自适应边界控制
Adaptive Boundary Control for a Class of Uncertain Heat Equations
摘要
Abstract
This paper investigates the adaptive state-feedback boundary control design for a class of heat equations with uncertain control coefficient and boundary disturbance. By Lyapunov method, the desirable controller is explicitly constructed, which only needs the boundary state of the system. It is shown that the closed-loop system state is L2 [0,1] stable, and particularly, the state converges to zero when the boundary disturbance vanishes. Moreover, by skillfully choosing the initial condition of parameter updating law, the restriction on the initial condition of the system is moderately relaxed, which is usually described by the so-called compatible condition in the related literature. A simulation example is presented to illustrate the effectiveness of the proposed method.关键词
