摘要:

用共轭方程的唯一延拓性证明了一类边界退化抛物系统的近似可控性, 即对任意的初值条件和目标函数, 存在一个控制函数, 使得该方程的解在有限的终端时刻近似达到目标函数.

关键词: 边界退化, 近似可控性, 边界控制

Abstract:

The author proved  the approximate controllability of a class of parabolic systems with boundary degeneracy by means of the unique continuation of the adjoint equation. Namely, under any initial conditions and desired conditions, there exists such a control function that the solution of the equation approximately reaches the desired terminal condition in a finite time.

Key words: boundary degeneracy, null controllability, boundary control
