The problem of strict bounded realness for linear systems with finite
discrete jumps is investigated in this paper. Several versions of the
strict bounded real lemma for such systems in both the finite and infi
nite horizon cases are obtained in terms of either a Riccati different
ial equation or Riccati differential inequality with finite discrete j
umps. These results encompass both existing continuous-time and discre
te-time strict bounded real lemmas.
