Title：Some Event-triggered schemes for multi-agent systems
Speaker: Professor Daniel W.C. Ho
Abstruct: Cooperative behaviors in networks involving autonomous mobile agents have aroused great research interest from different research communities due to their wide applications in various fields including the engineering field, robotics, and parallel computation. One of the important problems of cooperative behaviors is consensus which aims to design effective algorithms for communication and control of agents so that all members agree upon the same final state.
Most of these works assume that either agents get continuous access to the states of their neighbors or the controllers update themselves continuously via current states of agents. In order to lower the cost, a sample-data approach was proposed. In general, sampled-data control is essentially time driven and needs to estimate a conservative sampling period or average sampling period. Recently, a new approach is developed based on event-triggered. It has provided an alternative mechanism where agents broadcast their states or update controller only when they need, which is unknown in advance. That is, only when the condition is triggered, the agents will then take the sample of information or controllers take the corresponding action respectively. Compared with traditional control methods, even-driven controller has the advantages of lowering cost and saving energy. In this talk, we shall discuss various types of event-triggered techniques over different kinds of network topologies.
