Event-triggered consensus of multi-agent systems under directed topology based on periodic sampled-data
The event-triggered consensus problem of first-order multi-agent systems
under directed topology is investigated. The event judgements are only
implemented at periodic time instants. Under the designed consensus algorithm,
the sampling period is permitted to be arbitrarily large. Another advantage of
the designed consensus algorithm is that, for systems with time delay,
consensus can be achieved for any finite delay only if it is bounded by the
sampling period. The case of strongly connected topology is first investigated.
Then, the result is extended to the most general topology which only needs to
contain a spanning tree. A novel method based on positive series is introduced
to analyze the convergence of the closed-loop systems. A numerical example is
provided to illustrate the effectiveness of the obtained theoretical results
