Quantized-observer based consensus for fractional order multi-agent systems under distributed event-triggered mechanism

This paper investigates the consensus problem of general nonlinear fractional order multi-agent systems in a directed network under event-triggered mechanism. First, observers are designed for every agent based on the outputs of them. Second, taking the constrains of communication bandwidth and storage space into consideration, the uniform quantizers are used for each channel. Then, the consensus criteria related with the general algebraic connectivity of communication topology under event-triggered mechanism are derived, furthermore, the Zeno behavior is excluded. Finally, an example is given to shown the effectiveness of the proposed methods.
