关于时滞系统的平稳振荡

On the Stationary Oscillations of Retarded Systems

在讨论时滞周期系统的平稳振荡中，先给出一般时滞系统平稳振荡存在性的充要条件，并对非周期系统渐近性态给出一个实用结果，最后以对孤立子系统最弱假设讨论了时滞周期大系统的平稳振荡。

Abstract In this paper, stationary oscillations of periodic retarded systems are investigated. In the paper, a necessary and sufficient condition for the existence of stationary oscillations of general retarded systems is first given, a practical result is given then for non periodic systems, finally, stationary oscillations of large scale periodic retarded systems is investigated under the weakest condtions on isolated sub systems.
