New reliable H-infinity filter design for networked control systems with external disturbances and randomly occurring sensor faults

摘要

This paper deals with the reliable H-infinity-based filtering problem of nonlinear networked control systems in the presence of external disturbances and random sensor faults. More precisely, a random variable obeying the Bernoulli distribution is adopted to describe the failures of the network sensors. By employing the Lyapunov-Krasovskii functional method, delay-dependent criteria are developed to guarantee the existence of the designed filter with the prescribed H-infinity performance. Then, a design method is given to calculate the desired reliable filter parameters. An illustrative example is provided to demonstrate the effectiveness and usefulness of the established theoretical results. (C) 2016 Elsevier B.V. All rights reserved.
