Abstract
SummaryIn this paper, a secure cooperative control strategy which integrates the data‐driven control method and the backstepping framework is proposed for a class of discrete‐time nonlinear multiagent systems with denial‐of‐service (DoS) attacks. First, by designing special index functions, we overcome the algebraic loop problem in the backstepping framework to propose a data‐driven backstepping control method which does not use the Lyapunov theory to design the controller. Second, the problem of DoS attacks in communication channels is solved by switching topology strategy. Then, an event‐triggered mechanism based on synchronization error is used to save communication resources, which does not have a great negative impact on the control performance. Moreover, an event‐triggered cooperative strategy is constructed to ensure that all signals and tracking errors of the closed‐loop system are bounded. Finally, two simulation examples verify the effectiveness of the proposed control scheme.
