摘要
This paper studies the distributed consensus control for linear multi-agent systems under discontinuous communication and control updating.A fully distributed event-triggered adaptive control protocol with strictly positive minimum interevent time(MIET)guarantees is proposed.First,an event-triggered distributed adaptive control law without using prior global information of network topologies is presented,which achieves asymptotic consensus via discrete control updating and intermittent communication.Then,a hybrid adaptive event-triggering scheme with an internal timer is designed that is activated only when the timer decreases to zero from a specified positive value.Under the proposed triggering scheme,not only Zeno behavior is excluded but also a strictly positive MIET between any two consecutive events is guaranteed,which facilitates the physical implementation.In contrast to the existing related results,the proposed fully distributed protocol only needs low-frequency communication and control updating,while ensuring the strictly positive MIET property.Finally,a simulation example is given to illustrate the effectiveness of the theoretical results.
