伴随随机攻击的信息物理系统的同步控制
Synchronization control of cyber physical systems during malicious stochastic attacks

信息物理系统（CPS）广泛存在于现代基础设施体系中，例如未来智能电网、智能交通网络和公众健康系统等。该系统的安全是社会正常运行的关键。该文介绍了信息物理系统的物理层网络和信息层网络，这两层网络是相互依存的。提出了在存在随机攻击条件下，相互依存的信息物理系统的数学模型，该攻击既存在于物理层网络，也存在于信息层网络。该文研究了在存在随机攻击条件下，相互依存的信息物理系统的同步问题，并提出了一种自适应非线性控制器。利用Weiner过程将这些控制器加入到物理层网络中，以实现相互依存的信息物理系统的同步。数值模拟证明了理论结果是有效的。
Abstract：Cyber physical systems (CPSs) exist in many modern infrastructure systems, such as the future smart grid, smart transportation networks, and public health systems. CPS security is critical for normal operation of our society. The physical layer networks and the cyber layer networks are all complex networks that are interdependent. A mathematical model is given for the interdependent systems during stochastic malicious attacks, which exist in both the physical layer networks and the cyber layer networks. In addition, an adaptive nonlinear controller is given to synchronize interdependent CPSs during malicious stochastic attacks. The controller uses the properties of a Weiner process for the physical layer networks to synchronize the interdependent CPSs. Numerical simulations show the effectiveness of the theoretical results.
