Outline of Final Research Achievements

In this research, we have studied cyber security measures for large-scale networked control systems in the presence of malicious attacks from the viewpoint of control theory. As cyber attacks, we have considered data manipulation in measurement and control signals as well as jamming attacks in wireless communication. We have developed control and estimation techniques to mitigate the effects of such attacks. The main results include (i) resilient consensus algorithms for networks containing faulty/attacked agents which may prevent regular agents from reaching consensus and (ii) stability analysis for linear systems under jamming attacks and random packet dropouts. Our methods guarantee given security levels and control performance even when resources for communication and computation may be restricted.
