  • Abstract
    The singular perturbation approach to the analysis and design of two-time-scale systems is applied to the H∞ filtering problem. A sequential procedure is described to decompose the problem into slow and fast subproblems. In this procedure, a fast filter is designed first using the fast model; then a slow filter is designed under a condition on the value of the filter at infinity. A composite filter is formed as the parallel connection of the fast with the strictly proper part of the slow filter. The asymptotic validity of the composite filter is established.
