研究了具有局部黏弹性阻尼的弱耦合板-波系统的镇定问题.在适当的假设下,在Hilbert空间中,运用线性算子半群的Lumer-Phillips定理得到该系统的适定性;进一步,借助线性算子半群一致指数稳定的频域特征,用分片乘子法结合矛盾讨论证明了弱耦合板-波系统的一致指数稳定性.
Stabilization of the weakly coupled plate-wave systems with local viscoelastic damping
The stabilization of the weakly coupled plate-wave systems with local viscoelastic damping is studied.Under appropriate assumptions,the well-posedness of the system in Hilbert space is obtained by using the Lumer-Phillips theorem of linear operator semigroups.Furthermore,with the help of the frequency domain characteristics of uniformly exponential stability of linear operator semigroups,the uniformly exponential stability of weakly coupled plate-wave systems is proved by using the piecewise multiplier method combined with the contradiction discussion.
