Self-triggered H∞ fault detection for networked control systems with convex polytopic theory

This paper is concerned with the self-triggered H-infinity fault detection problem for a class of networked control systems with simultaneous input and output disturbances. The aim of the addressed problem is to design a fault detection filter, by means of uncertain polytopic theory, such that faults can be detected through the self-triggered nonuniform sampled output. By using the stochastic analysis techniques, sufficient conditions are established for the existence of the desired H-infinity fault detection filter whose parameters are then obtained by solving the linear matrix inequality. Finally, a simulation example is presented to illustrate the effectiveness of the developed fault detection design scheme.
