This article investigates the problem of output feedback control of fractional-order ( 0 < δ < 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 is proposed with 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 applying singular value decomposition matrix, and linear matrix inequalities (LMIs), observer and the controller gain matrices are obtained. Finally, DC–DC power converter model is used to demonstrate the efficiency of the proposed methodology.
