  • Abstract
    This paper deals with the problem of H2 filtering for linear discrete-time systems with time-varying uncertain parameters. The parameters enter affinely in the matrices of the system state-space model and their admissible values and rates of variation are assumed to belong to a given polytope. Based on parameter-dependent Lyapunov functions, two LMI based methods are proposed for designing linear stationary asymptotically stable filters which ensure a prescribed H2 performance.
