• Multi-agent systems
• H-infinity control
• consensus
• parameter uncertainties
• Lipschitz nonlinear
• output feedback

In this study, the consensus problem is discussed for a class of multi-agent systems with unknown Lipschitz nonlinear dynamics, external disturbances, and parameter uncertainties under a fixed directed graph. By some model transformations, the consensus problem becomes a reduced-order H-infinity control problem. Based on the reduced-order control problem, sufficient conditions to achieve the consensus with the desired H-infinity performance are presented. These conditions are to check the solvability of only one linear matrix inequality (LMI) and the dimension of the LMI independent of the number of agents in the network. Moreover, an algorithm is proposed to design the dynamic output feedback controller. Simulation on networked multi-agents is provided to show the effectiveness of the theoretical results.
