Fast Finite-Time Secure Control for Nonlinear Systems under Dynamic Event-triggered Mechanism

Abstract This paper addresses the fast finite-time secure control problem for the nonlinear system subjected to deception attacks. To enhance the resilience of the nonlinear system with faster convergence rate, a fast finite-time secure controller (FFSC) with an adaptive compensation law is designed, which deals with the damage effects from the deception attacks. Moreover, for the purpose of alleviating the network burden, a dynamic event-triggered mechanism is established, which is regulated by the internal variable generator contains the error norms with the fractional power. Furthermore, the fast finite-time stability of the closed-loop system and the Zeno behavior elimination of the proposed DETM are rigorously proved, respectively. Consequently, the simulation results demonstrate the effectiveness of the proposed method.
