Event based practical fixed-time consensus control for heterogeneous nonlinear multiagent systems.

This paper solves the problem about the practical fixed-time consensus for heterogeneous nonlinear multiagent systems (MASs) with one-order dynamic models. First, the event trigger functions are introduced to reduce the communication burden of the network. And the adaptive laws are present which aim to deal with the instability caused by the uncertain parameters. By combining them, the control input is designed to make the system practical fixed-time consensus. Then we prove the boundedness of the variables and there is no Zeno phenomenon in the discussed systems under the control scheme. Comparing with the existing works, this paper focus on the distribute uncertain heterogeneous nonlinear MASs, has a practical fixed-time consensus and takes a balance between communication burden and accuracy. Finally, a comparison experiment is illustrated. [ABSTRACT FROM AUTHOR]
