Secure Consensus Control for Time-Varying Multi-Agent Systems with Mixed Types Attacks

Secure control plays a important role in consensus control of multi-agent systems, which significance has made the security performance a main concern. This paper considers the secure consensus control problem for time-varying multi-agent systems with randomly occurred mixed types attacks. Different existing studies have concerned with secure control by assuming specific type attacks, the general of mixed types attacks model is considered. Specifically, DoS and FDI attacks are considered for measurement and control channels, and they are assumed to obey Bernoulli process. To analyze the secure consensus of the resulting closed-loop MASs, the stochastic analysis technique is introduced, based on which sufficient criteria for the H
_∞
controller are obtained, ensuring the consensus and the prescribed H
_∞
performanc. The proposed control approach is demonstrate by the controller utilized in MASs subject to mixed types attacks.
