摘要:
对具反馈边界控制问题中的一维带黏性阻力和恢复力的波方程系统,在函数空间中将其化为抽象Cauchy问题,其系统算子具预解紧且是某C0压缩半群的生成元,得到了系统算子的谱分布特征,包括其谱点实部的上确界小于零以及谱点位于某平行于虚轴的有限带域中,为进一步讨论该系统的稳定性、可控性及Riesz基性质奠定了基础.
Abstract:
For the wave equation system with one-dimensional viscous resistance and restoring force in the feedback boundary control problem, it is transformed into an abstract Cauchy problem in the function space, and the system operator is pre-compacted and is the generator of a certain C0 compression semigroup, and the spectral distribution characteristics of the system operator are obtained, including that the supremum of the real part of the spectral point is less than zero and the spectral point is located in a finite band domain parallel to the imaginary axis, which lays a foundation for further discussion of the stability, controllability and Riesz basis properties of the system.
