英文摘要： In this project, the event-triggered control and filtering problems are investigated for networked nonlinear stochastic systems. The incomplete information caused by the network devices with limit capacity or the external stochastic disturbances is fully discussed and the nonlinear and stochastic factors as well as their variety laws are studied deeply. Then the kinetic model with measurement model is established that is capable of representing the networked-induced incomplete information and nonlinear and stochastic natures of the systems under consideration. Various event-triggered mechanisms are analyzed and their features are also discussed in detail including the advantage and disadvantage when the event-triggered mechanisms are applied in the control and filtering problems. After that, we investigate the problems of analysis and synthesis for the nonlinear stochastic event-triggered controller and filter in the networked environment. Based on it, the event-triggered control and filtering approaches are further developed to solve the consensus control problem for the multi-agent systems and the distributed filtering problem in sensor networks. Finally, the results obtained are demonstrated in experimental platform which is established for the study of the localization problem for multiple mobile robots. The research results derived in this project are of a great significance both in theory and application prospect.
