Abstract：A quantization controller based on observers with event-triggered schemes is designed for the situation where the state of complex network is not available.In order to reduce communication times and computation burden,event-triggered schemes and logarithmic quantizers are introduced.Firstly,a distributed state observer is designed for the unmeasurable system state,and a joint error model of synchronization error and observation error is established considering the influence of event-triggered schemes and quantization on the system.Secondly,according to the Lyapunov stability theory,Schur Complement lemma and Cauchy Inequality,the sufficient conditions for the asymptotic stability of the joint error system with linear matrix inequality(LMI)form are obtained.At the same time,the state observer and controller gain solving methods are given.Then,it is proved that the Zeno behaviour can be excluded for the proposed event-triggered schemes,and that the minimum lower bound of the event-triggered interval is obtained.Finally,a numerical example is given to validate the effectiveness of the proposed method.
