Event-triggered formation control of discrete-time multi-agent systems with input time-delay

The event triggered formation control problem for a class of discrete-time multi-agent systems described by complex difference equations is studied by using complex Laplacian.The event-triggering time sequence for each agent is defined by the triggering function which includes the state information and an exponential decay item. The event triggering time series are determined according to the event triggering conditions. The design of triggering function only uses the discrete-time information of its neighbors, avoids continuous communication among neighboring agents, andgreatly saves the limited bandwidth. The event-triggered controller for each agent is designed and the controller update frequency is reduced. Continuous updating of controllers is avoided. The input time-delay is also considered. Under the event-triggered control strategy, a sufficient condition for achieving similar formation of arbitrary given formation is obtained, and the range of input delay is given. Furthermore, the Zeno-like behavior of the event-triggering time sequence is excluded. Finally, a numerical simulation is presented to show the effectiveness of the theoretical result.
