Robust Finite-time Consensus Tracking for Second-order Multi-agent Systems with Reduced Communication

In this paper, we study the finite-time consensus tracking problem for second-order multi-agent systems with input uncertain dynamics and external disturbances. Robust finite-time consensus tracking controllers are designed with reduced communication. The proposed controllers achieve finite-time consensus tracking in the presence of bounded input uncertainties with only relative position information under general directed communication topologies. Both the cases of static and dynamic leaders are considered. An application in the coordinated attitude control of multiple satellites is used as an example to illustrate the effectiveness of the proposed control strategies.National Natural Science Foundation of China [61473003]CPCI-S(ISTP)6086-609
