Abstract

This paper investigated the fault detection problem in finite-frequency domain for nonlinear networked system under stochastic cyber-attack. To save limited network resource, this paper introduced a novel dynamic event-triggered scheme. Firstly, under the consideration of fault sensitivity and disturbance robustness, this paper converted the addressed fault detection problem into an auxiliary H-/H∞ filtering problem by augmenting the states of the original system and the fault detection filter. Taking sector bounded nonlinearity and stochastic cyber-attacks into consideration, the design of H- performance index included the frequency characteristics of fault signals. Combined with finite-frequency input characteristics, this paper proposed the joint design algorithm for fault detection filter and dynamic event-triggered scheme under the finite-frequency fault input. Finally, a simulation example of stirred tank reactor system verifies the effectiveness of the proposed method.
