The lab studies how to coordinate widely distributed systems through communication.

AboutAbout the lab
Linking control with information and communication in new ways
The Systems and Control Lab studies the theory of systems and control and its applications.
It focuses in particular on the relationship between control and the theory of information and communication.
The lab works on networked control systems and cyber-physical systems, in which agents spread over a wide area use communication to achieve complex control objectives.
It tackles questions such as how to achieve high-performance control with a limited amount of communication, and how to ensure the security of control systems.
Key terms
- Systems and control
- The technology of deciding inputs and adjusting them so that machines and networks behave as intended
- Agent
- Here, an individual device or program that makes its own decisions and acts on them
- Cyber-physical system
- A system that connects physical objects through communication, moving back and forth between information processing and physical action
ResearchResearch themes
The lab studies theory related to systems and control, and its applications. Taking a systems-theoretic approach, it works broadly on control systems that operate over communication channels, from fundamental theoretical problems to design methods with applications in mind.
*Illustrative imageControl over Networks
The lab studies mechanisms by which agents spread over a wide area use the internet or wireless communication to achieve complex control objectives. How to achieve high-performance control with a limited amount of communication is a fundamental question that is also theoretically deep.
*Illustrative imageDistributed Algorithms and Fault Tolerance
The lab studies distributed algorithms in which many agents coordinate by exchanging information, and the properties that allow such systems to keep working even when some of the agents fail.
*Illustrative imageCybersecurity of Control Systems
The lab works on how to ensure the cybersecurity of control systems from the viewpoints of both control and information.
*Illustrative imageDistributed Randomized Computation of PageRank
The lab studies methods for computing PageRank, which is used in search engines, probabilistically by dividing the computation among many computing agents.
