Fault Detection of Networked Control Systems Subject to Uncertain Time-Varying Delay and Packet Dropout

Abstract

This paper focuses on fault detection of networked control systems with both time-varying delay and packet dropout. Different from some existing results, in this paper, network-induced delay is not limited to be an integer multiple of the sampling period, and packet dropout is present in both sensor-to-controller link and controller-to-actuator link. The method in this paper can be regarded as an expansion of an existing work of the authors' group, which deals only with network induced delay without considering packet dropout in the design.
