中文摘要: 间歇性控制策略是介于连续控制和脉冲控制之间的一种新的控制策略,对于它的研究具有重要的理论和应用价值。首先,本项目提出了一种具有非周期、随机特征的间歇性控制策略。然后,本项目研究了复杂网络在该策略下的多种动力行为,包括复杂网络的稳定性、鲁棒性、网络中的传播机理、相继故障机理、协调控制等多个方面,探讨了网络动力行为与网络结构、间歇性控制策略之间的关系。在研究方法上,本项目建立了处理非周期间歇性控制策略的新的理论结构,从而为实现复杂网络在非周期间歇性控制下的各种动力行为提供了可行方法。不仅如此,由于网络环境的变化或者参数不可观测等因素,本项目还将考虑复杂网络在间歇性控制策略下的自适应演化问题,设计相应的自适应演化规则并进行理论证明。本项目的研究,将为间歇性控制策略下的复杂网络建模与分析提供解决方案,丰富和发展复杂网络理论,为网络的演化和调控提供理论指导,促进复杂网络在其它领域的交叉融合和应用。

英文摘要: Intermittent control strategy (ICS) is a new type of control strategy, which can be regarded as a strategy between continuous control and impulsive control. The investigation of ICS will play an important role in both theoretical researches and real applications. At first, this proposal presents an intermittent control strategy, which has the non-periodic, random characteristics. Then, the proposal will study several dynamical behaviors of complex networks under the strategy, including the network stability, robustness, the propagation mechanism in the network, cascading failure mechanism of network, network coordination and control, etc. The proposal will also discuss the relationship between dynamical behaviors and the network structure and ICS. As for research methods, this proposal will establish a theoretical framework to deal with non-periodic ICS, so as to provide a viable method to achieve the dynamical behaviors of complex networks under the non-periodic ICS. Moreover, due to changes in the network environment and exists of unobservable parameters, this proposal will also consider the adaptive evolution problem of complex networks under the ICS, design appropriate adaptive evolution rules and give the corresponding theoretical proofs. The investigation of this proposal will provide solutions for complex
