中文摘要： 网络化控制系统中，由于网络有限的通讯带宽资源，传统的时间驱动的控制策略显现出固有的局限性。为了节省有限的通讯资源，近年来,基于事件触发机制的网络化控制受到越来越多研究者的关注。本项目研究基于事件触发机制的时滞复杂网络同步与状态估计问题，首先，考虑由网络化引起的时滞、噪声等因素，建立起能够更加精确刻画时滞、非线性以及噪声等特性的动力学模型。其次，系统分析事件触发原理，详细讨论各种事件触发机制的优缺点，研究有效的控制方案，来保证复杂网络同步。在此基础上研究基于事件触发机制的时滞复杂网络同步问题，基于事件触发机制的多性能指标约束下的时滞复杂网络同步问题以及基于事件触发机制的时滞复杂网络的状态估计问题。综合运用脉冲系统方法，Lyapunov稳定性理论、比较定理方法、参数变异法等理论与方法导出基于事件触发机制的复杂网络同步与状态估计的解析判据。本项目的研究将丰富复杂网络同步与状态估计理论。

英文摘要： In networked control systems, the limited bandwidth resources encumbers the wide applications of time-triggering sampled data control to practical networks. In order to save the limited bandwidth resources, control of networked control systems with event-triggering mechanism has received a lot of research attentions. In this project, we will investigate the synchronization and state estimation of delayed complex networks with event-triggering mechanism. By analyzing the effects of time delay and noise on network dynamics, the kinetic model will be established that is capable of representing the networked-induced time-delay, nonlinear and noise. Then, we will analyze the advantages and disadvantages of various event-triggering mechanisms to find an effective event-triggering mechanism. After that, we study synchronization of delayed complex networks with event-triggering, synchronization of delayed complex networks with various constraints and state estimation of delayed complex networks. By utilizing the impulsive system approach, the Lyapunov stability theory, comparison principle and the formula for the variation of parameters, we will derive the criteria for the involved networks to be synchronized with event-triggering mechanism. The investigation of this project will enrich the theory on synchronization and state estimation of complex networks.
