报告摘要:
       Distributed cooperative control of multi-agent dynamic systems has attracted increasing attention in the controls and robotics communities. The research on this topic has a wide range of engineering applications, including multivehicle formation control, multi-robot coordination, attitude synchronization of spacecrafts, deployment and scheduling of sensor networks, etc. One of the fundamental research lines on this topic is consensus design. The objective of consensus is to design distributed control laws using local neighboring information so that the states of a team of agents reach an agreement. For multi-agent engineering systems, there exist extensively disturbances and unmodelled uncertainties, which make the consensus design challenging. In this talk, we will present an identifier-based method to achieve robust consensus for multi-agent dynamic systems with disturbances and unmodelled agent dynamics. An identifier is first designed to estimate the unknown disturbances and unmodelled agent dynamics. Based on this identifier, a consensus protocol is designed to enable robust consensus tracking using local information obtained from neighboring agents.
