| 英文摘要 |
| This paper is to stabilize a 1-D wave equation with an anti-damping by boundary control. To use the backstepping
method of boundary control, a new transformation of two kernel functions is introduced. The equations of kernel
functions are more complicated mathematically. By some mathematical skill, solutions of the kernel equations are
constructed. Finally, the inverse transformation is attained. Through boundedness of the transformation and its inverse,
stability of the closed-loop system is established. |
