  • Separator-type robust stability theorem of sampled-data systems allowing noncausal LPTV scaling

    Hagiwara Tomomichi

    … This paper derives a necessary and sufficient condition for robust stability of sampled-data systems, which is stated by using the notion of separators that are dealt with in an operator-theoretic framework. … Such operator-theoretic treatment of separators provides a new perspective, which we call noncausal linear periodically time varying scaling and leads to reducing conservativeness in robust stability analysis. …

  • Linear periodically time-varying scaling and its properties

    Hagiwara Tomomichi , Mori Ryouta

    … Stimulated by a general necessary and sufficient condition for robust stability of sampled-data systems stated in an operator-theoretic framework, we introduce a novel technique called linear periodically time-varying (LPTV) scaling. … We then give a simple example of sampled-data systems in which this new scaling allows exact robust stability analysis for static uncertainties while the conventional linear time-invariant (LTI) scaling fails to do so. …
