線形むだ時間システムのむだ時間非依存形安定化について

抄録

A method of delay independent stabilization of a linear system is considered. The state of the system is measured through the output and therefore only a limited part of the state variables is directly measured.
In this paper, the delay independent stability of considered systems are proven with the help of the known properties of certain delayed differential equations, without using Lyapunov functions or functionals. Delays contained in the system may vary with time and moreover all delay functions may be different from each other.
If the system is observable and statisfies a few additional conditions, the same condition as for the case with all measurable state variables, that has already been published, is obtainable in our case.
