Secure consensus for multiagent systems with hybrid cyber attacks: A multi-round-robin protocol-based approach

This article addresses secure consensus of discrete multiagent systems (DMASs) with information exchange under Multi-Round Robin Protocol (MRRP). Since the information exchange among agents is via the constrained networked transmission channel, it implies that the communication resources should be fully utilized. To overcome this issue, MRRP is employed to adjust the data packet transmissions and conserve the limited network resources. Considering that the transmitted signals may be tampered by malicious attacks during transmission process, an new control strategy is presented taking the negative effects of the deception and injection attacks into account. Based on the augmented system model, a sufficient condition is attained. Moreover, the distributed controller gain is obtained such that the DMASs reach consensus with definite bound in mean-square sense. One simulation example is exploited to demonstrate the validity of the acquired consensus control strategy.
