    Robust H-infinity filtering for a class of linear parameter-varying systems
    (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001) Mahmoud, MS; Boujarwah, AS
    In this paper, we investigate the problem of H-infinity filtering for a class of linear parameter-varying (LPV) systems in which the state-space matrices depend affinely on time-varying parameters. We employ the notion of affine quadratic stability using parameter-dependent Lyapunov functionals. We develop a linear parameter-dependent filter such that the estimation error is affinely quadratically stable with a prescribed performance measure. It is established that the solvability conditions can be expressed by linear matrix inequalities which are then evaluated at the extreme points of the admissible parameter set. Simulation results of a typical example are presented.
