第37届中国控制会议

作者： Hang Guo Qirui Zhang Kun Liu Yuanqing Xia School of Automation Beijing Institute of Technology

This paper is concerned with the filter design problem for a class of linear networked control systems in the presence of unknown disturbances with distributed sensors subject to randomly occurring deception attacks. The round-robin protocol is utilized to regulate the signal transmission between sensors due to limited communication resource. Sufficient conditions are established to ensure the desired performance by applying the discrete-time Wirtinger’s inequality. Furthermore, a corresponding distributed filter is designed to guarantee security. Finally, a numerical example is given to illustrate the effectiveness of the proposed filter design scheme.
