摘要
研究T im oshenko梁点反馈的稳定性.用线性算子半群方法证明了闭环系统的适定性,并应用算子谱特征得到了闭环系统的强渐近稳定性的充分必要条件.同时,给出了保守系统的几个能观性不等式.
This paper studies feedback. The well posedness of cl semigroup method, and the stron operator spectrum characteristics conservative system are given. the stability of Timoshenko beam with a pointwise osed loop systems is proved with the linear operator gly asymptotical stability of closed loop systems by is obtained. Also some observability inequalities to
