Scalable Control Design for Cyberphysical Systems

Back
Abstract:
Advances in computation, communication and embedded systems are enabling the deployment of cyberphysical systems of unprecedented complexity. This trend must be paralleled by new approaches in networked control, adapted to large-scale interconnections of subsystems that interact and exchange information. In this talk we will address scalability of control design, focusing on methods where the complexity of synthesising a local controller is independent of the size of the overall system. Scalable design is especially needed in industrial applications where the number of subsystems changes over time, sensors and actuators are frequently replaced, or no global model of the plant is available. We will present methods for plug-and-play design of local controllers, enabling the seamless addition and removal of subsystems while denying automatically plugging in and out requests that are dangerous for safety or stability.

As an application, we will discuss plug-and-play design of voltage controllers for microgrids, allowing connection and disconnection of generation units while preserving overall voltage stability. This is a first step towards the deployment of multi-owner, autonomous energy islands with flexible size and topology. The final part of the talk will be devoted to research perspectives towards enhanced adaptivity and autonomy of cyberphysical control systems.
