Control of Network Systems with Signed Dynamical Interconnections

This project aims to develop the theories and tools for engineering dynamical networks with signed interactions that arise from a variety of applications where both cooperative and adversarial agent interactions coexist. The state-of-the-art methods in control and identification of dynamical multi-agent networks assume a single relation type, whereas signed dynamical networks further specify how different types of node relations influence the network dynamics. Controllability theories, identification algorithms, and trust management methods of such signed network systems exploiting the additional network sign structure will enable the robust and secure design of systems such as online review systems, smart grids, and cyber-physical systems.
