Reconfiguration and Cyber-Attack Tolerant Control for Nonlinear Multi-Agent Systems

This work deals with the development of an observer-based control/monitoring against Cyber-Attacks (CAs) for interconnected cyber-physical systems. The latter can disconnect an entire node in a network as a result of attacks on control and/or observer chains. The Cyber-Attack Tolerant Control (CATC) of nonlinear Multi-Agent System (MAS) is treated with the consideration of observer-based control gains as well as the optimization of the coupling parameters for each for each scenario using Linear Matrix Inequality (LMI). Indeed, each state of the global nonlinear system achieves a Laplacian matrix describing its topology of interconnections between the various nodes (master and followers). An algorithm has been proposed to guarantee the cyber-security of MAS with the consideration of two issues related to stabilization and the tracking control problems. The theoretical results are validated by simulations on a nonlinear MAS consisting of a master (reference) and 5 followers.
