✦ Synopsis

In this paper we establish some useful properties of three Riccati equations appearing in the standard H∞-control problems for continuous and discrete-time time-varying systems. We then give necessary and su cient conditions for the existence of a suboptimal controller by three conditions involving two independent Riccati equations with a coupling inequality.

Necessary and sufficient conditions for the existence of the stabilizing solution to the time-varying discrete Riccati equation are derived in terms of the so-called Ben Artzi Gohberg dichotomy. It is shown that the problem of such existence conditions is strongly related to that of unique solvabili

The standard state space solution of the finite-dimensional continuous time quadratic cost minimization problem has a straightforward extension to infinite-dimensional problems with bounded or moderately unbounded control and observation operators. However, if these operators are allowed to be suffi
