In the first part of the paper, robust consensuswas discussed for continuous-time multi-agent systems withuncertainties in the dynamics. As an application of the robustconsensus analysis, this part of the paper further investigatesdistributed multi-agent coordination via event-triggeredstrategies, where the control input of each agent is piecewiseconstant. Each agent chooses the instances to update itscontrol input by checking whether its state error meets a giventime-dependent function or not. Proper triggering conditionsare given for the system to reach a global consensus usingpiecewise costant control with directed time-varying communicationgraphs under neighbor-synchronous and asynchronousupdating protocols, respectively.
