本项目拟从物理层中智能体的多样性和通信层受限角度，研究网络攻击下信息物理系统的分布式安全协同控制问题。主要研究内容如下：(1)提出几类异构信息物理系统，结合攻击特点设计分布式一致性协议，建立研究连续时间和离散时间信息物理系统安全一致性问题的统一框架；（2）研究采样量化通讯下信息物理系统的安全一致性，考虑不同量化器对一致性的影响，探索同时面向优化性能表现与降低数据需求两个不同方面的折中处理；(3)构建信息物理系统安全协同控制可视化动态仿真平台和多机器人物理实验平台。本项目的研究成果将进一步丰富和发展信息物理系统与信息安全的相关理论。

This project will consider the distributed coordination control problem for cyber-physical systems of heterogeneous agents and limited communication under adversarial attack. The specific objectives of the project include: (1) The first objective is to propose heterogeneous cyber-physical systems, design consensus protocols based on the character of attacks, and present a unified framework for both discrete-time and continuous-time cyber-physical systems from different perspectives; (2) The second objective is to investigate the quantized resilient consensus using sampled information. How different quantizers affect the performances the consensus-type coordination algorithms and how to balance the resilient consensus performance and data demanded will be studied; (3) The third objective is to build visual simulation platform and physical experiment platform for resilient coordination protocols. This project will enrich and develop the theory in security control of cyber-physical systems by introducing new models and designing new algorithm.
