This article investigates the consensus problem of leader-follower multiagent systems with semi-Markovian jump parameters, introducing adaptive event-triggered communication and double quantization for consensus protocol design. A sufficient condition is established for stability under adaptive event-triggered condition, and a consensus controller is developed by matrix inequality approach. A numerical example is provided to demonstrate the effectiveness of the developed consensus controller.
In practice, many dynamical systems can be modeled by multiagent systems (MASs) with different operating modes. The consensus problem of leader-follower MASs with semi-Markovian jump parameters is investigated in this article. First, to save the bandwidth resources of the MASs, adaptive event-triggered communication and double quantization are introduced to design the consensus protocol, in which the event-triggered threshold is dynamically adjusted instead of being a constant, and not only the data from the agents to the consensus controller but also that from the controller to the agents, are both quantized. Next, a sufficient condition is established to ensure the stability of the consensus error system under the adaptive event-triggered condition, and then the consensus controller is developed by matrix inequality approach. Finally, a numeral example is given to demonstrate the effectiveness of the developed consensus controller.
