Secure consensus of multiagent systems with input saturation and DoS attacks

The secure leader-following consensus problem of multiagent systems with both denial-of-service (DoS) attacks and input saturation constraints is investigated in this note. The low-gain technique has been developed for designing the distributed control protocol for each agent. Explicit analysis of the duration and the frequency of the DoS attacks have also been presented in order to guarantee the desired secure consensus. The stability analysis of the closed-loop system is conducted by using the Lyapunov function method. Some simulations are presented for validating the effectiveness of the presented strategy.
