Goals

This course reviews the past and present results in the area of decentralized control of complex dynamical systems. Elements from control theory and optimization are merged in order to provide useful tools which will be further applied to various problems involving multi-agent dynamical systems and interconnected systems in general.
An emphasis is laid on centralized vs distributed vs decentralized approaches, decomposition, information structure constraints, the stabilization and the tracking performances of each agent, robustness. The presented theory answers the fundamental questions of how to break down a given control problem into manageable subproblems which are only weakly related to each other and can be solved independently.
The tools the students will acquire during the course in optimization-based control (via distributed/hierarchical approaches) will be used for some application benchmarks like control and coordination of multiple (aerial, aquatic) drones, energy management in DC microgrid systems and water distribution networks.
