Summary:
Networked control systems (NCSs) are created by the integration of advanced communication networks, control systems, and computation techniques. This integration enhances efficiency and reliability at the expense of increased complexity and reduced security . For example, the reliance of NCSs on communication networks exposes these systems to attack vectors targeting generic networks. RANCS focuses on resilient design of NCSs under faults, failure and attacks. We focus on mathematical framework for an NCS under common types of attack is presented, i.e., denial of service (DoS), false data injection (FDI), and time delay switch (TDS) attacks. Thereafter, the framework is used to developed attack detection and resilient control and communication methods such as designing an algorithm based on adaptive channel allocation and state estimation techniques to compensate for the destabilizing effects of attacks.
