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