Reachable-Set-Based Fault Detection for Switched Delayed Systems With Deception Attacks

This paper investigates the fault detection problem of a class of switched delayed systems (SDSs) affected by deception attacks. Utilizing the framework of output reachable set theory, a fault detection methodology reliant on reachable set is established to effectively tackle the fault detection challenge in the presence of bounded peak interference inputs, fault signals, and attack signals. By jointly constructing the combined switching strategy and time-dependent multiple Lyapunov-Krasovskii functional (TMLF), sufficient conditions are derived for the design of fault detection filter (FDF), and the corresponding logic relationship for fault detection is developed. Ultimately, an example is ultimately presented to corroborate the efficacy of the obtained findings.
