摘要：

In this paper, a robust H-infinity filtering problem is considered for a class of discrete-time non-linear systems. Based on the Lyapunov method, a design criterion of the robust H-infinity filter guarantee not only the stability but also the prespecified upper bound of H-infinity norm from the disturbance inputs to error state outputs. The design condition can be solved easily by efficient convex optimization algorithms. Numerical examples show the effectiveness of the proposed method. (C) 2011 Elsevier Inc. All rights reserved.
