Networked control systems
Summary
This course offers an introduction to control systems using communication networks for interfacing sensors, actuators, controllers, and processes. Challenges due to network non-idealities and opportunities offered by communication will be analyzed.
Content
Control systems relying on communication networks find several applications in emerging fields such as cyberphysical systems and the Internet of Things. The exchange of information over imperfect channels raises the problem of studying how networks impact on the real-time behaviour of systems. The first part of this course will focus on methods for analysing stability and performance of networked control systems. In the second part, instead, we will study how to exploit networked architectures for realising coordinated behaviours among subsystems. We will introduce consensus algorithms and illustrate various applications to sensor networks, cooperative robotics, analysis of opinion dynamics and electric systems.
