Output feedback control for uncertain fractional-order system subject to deception cyber-attacks via observer-based event-triggered scheme 1

This article investigates the problem of output feedback control for fractional-order (0 1) uncertain systems subject to deception attacks based on observer-based event-triggered scheme. Compared to the existing deception attacks, the proposed model consists of two random deception attacks on the fractional-order system. To decrease communication resource usage while maintaining desired system performance, an observer-based event-triggered scheme has been proposed. But it also has no Zeno behavior. The Lyapunov functional theory is used to establish sufficient conditions for ensuring the global asymptotic stability of an uncertain fractional-order system. By generalized applying singular value decomposition matrix, linear matrix inequalities (LMIs), we obtained the observer, and controller gain matrices. Finally, DC-DC power converter model is used to demonstrate the efficiency of the proposed methodology.
