摘要:

该文讨论了由一个半线性退化抛物方程与半线性热方程构成的串联系统的零能控性. 这里控制函数仅施加在一个方程上. 证明的关键是建立适当的能观性不等式.

关键词: 零能控, 串联系统, 退化方程

Abstract:

This paper deals with null controllability of a cascade system governed by a semilinear heat equation and degenerate parabolic equation under appropriate assumptions. The control acts on only one equation . The critical point is to establish suitable observability inequalities.

Key words: Null controllability, Cascade system, Degenerate equation
