This study investigates the leader-follower robust H-infinity consensus problem of heterogeneous multiagent systems with denial of service attack, and provides sufficient conditions for solvability. The results show that the consensus protocol design can be transformed into static output feedback control problems, and the gains of the controller can be determined by solving linear matrix inequalities.
This paper investigates the leader-follower robust H-infinity consensus of heterogeneous multiagent systems with denial of service attack, where different attack intensities are considered. A switched system model is introduced to model such an attack phenomenon. Then, sufficient conditions to guarantee the solvability of the robust output consensus problem are obtained, and the quantitative relationship between the consensus performance and attack parameter is established. It is shown that the consensus protocol design problem can be transformed into two static output feedback (SOF) control problems. It is also shown that the SOF controller gains can be determined by solving some linear matrix inequalities without the knowledge of the probability information of each attack. Finally, the effectiveness of the control protocol is demonstrated by a simulation study.
