| Outline of Final Research Achievements |
This paper aims at an operator theoretic approach to sampled-data and time-delay systems, in which compression operators play a key role especially when we deal with their stability analysis through scaling-based approaches. It studies such operators defined on a space different from those in conventional studies and covers analysis and synthesis problems relevant to essentially bounded signals. For time-delay systems, such a change in the space does not affect the stability definition itself but could be effective in alleviating some numerical issues in the stability analysis. In sampled-data systems, the use of the new space is connected to the upper/lower bounds analysis of the L-infinity induced norm and a relevant synthesis problem, which can be tackled through piecewise constant and piecewise linear approximations of signals. The effectiveness of the discrete-time arguments relevant to the scaling approach is also confirmed through experiments with a real system.
