| Abstract: | This paper studies the stability of Euler- Bemoulli beam with a pointwise feedback bending moment . The authors prove well posedness of the closed loop system by the method of linear operators semigroup and show that strongly asymptotical stability of closed loop system by spectnan characteristics of the operator. Also the authors give some observability inequalities to conservative system. |
