In this paper we investigate the closed-loop performance of a sampled-data control system by utilizing exact discretization techniques. In particular, for an H2 performance measure we give exact expressions for the closed-loop cost for a given sample interval h. After applying discrete-time LQG synthesis to the sampled-data system, the achievable performance is evaluated for fast sampling near ...
