Decentralized Event-Based Communication Strategy on Leader-Follower Consensus Control

الملخص EN

This paper addresses the leader-follower consensus problem of networked systems by using a decentralized event-based control strategy.

The event-based control strategy makes the controllers of agents update at aperiodic event instants.

Two decentralized event functions are designed to generate these event instants.

In particular, the second event function only uses its own information and the neighbors’ states at their latest event instants.

By using this event function, no continuous communication among followers is required.

As the followers only communicate at these discrete event instants, this strategy is able to save communication and to reduce channel occupation.

It is analytically shown that the leader-follower networked system is able to reach consensus by utilizing the proposed control strategy.

Simulation examples are shown to illustrate effectiveness of the proposed control strategy.
