Zhang, Jinhui, Xia, Yuanqing and Shi, Peng (2009) Parameter-dependent robust H-infinity filtering for uncertain discrete-time systems. Automatica, 45. pp. 560-565. ISSN 0005-1098
Abstract
This paper is concerned with the problem of parameter-dependent H∞ filtering for discrete-time systems with polytopic uncertainties. The uncertain parameters are supposed to reside in a polytope. Being different from previous results in the quadratic framework, the parameter-dependent Lyapunov function is used in this paper. Both full- and reduced-order filters are designed, which guarantee the asymptotic stability and a prescribed H∞ performance level. The filter parameters can be obtained from the solution of convex optimization problems in terms of linear matrix inequalities, which can be solved via efficient interior-point algorithms. Numerical examples are presented to illustrate the feasibility and less conservativeness of the proposed method.
