摘　　要：This paper addresses the ultimate boundedness control problem for a class of networked nonlinear systems with the round-robin(RR)protocol and uniform quantisation.The communication between sensor nodes and the controller is implemented via a constrained communication channel.The quantised output of the system is transmitted to the remote controller through a communication channel subject to a transmission delay.For the purpose of alleviating possible data collision,the well-known RR communication protocol is deployed to schedule the data transmissions.On the other hand,the uniform quantisation effects of the network are characterised by a round function(i.e.the nearest integer function).The purpose of the addressed problem is to design an observer-based controller for the networked nonlinear systems such that,in the presence of RR protocol and uniform quantisation effects,the closed-loop system is ultimately bounded.The controller is designed based on mean square stability analysis and Lyapunov-like method.A set of sufficient conditions for the ultimate boundedness of the closed-loop system are established and,on the basis of which,the desired controller gains are obtained by solving a set of linear matrix inequalities.The effectiveness of the proposed method is verified by numerical examples.
