Resistance Distance and Control Performance for bittide Synchronization
Sanjay Lall, Calin Cascaval, Martin Izzard +1
We discuss control of bittide distributed systems, which are designed to provide logical synchronization between networked machines by observing data flow rates between adjacent sy…
Modeling and Control of bittide Synchronization
Sanjay Lall, Calin Cascaval, Martin Izzard +1
Distributed system applications rely on a fine-grain common sense of time. Existing systems maintain the common sense of time by keeping each independent machine as close as possib…
An Algebraic Approach to the Control of Decentralized Systems
Laurent Lessard, Sanjay Lall
Optimal decentralized controller design is notoriously difficult, but recent research has identified large subclasses of such problems that may be convexified and thus are amenable…
Convexity of Decentralized Controller Synthesis
Laurent Lessard, Sanjay Lall
In decentralized control problems, a standard approach is to specify the set of allowable decentralized controllers as a closed subspace of linear operators. This then induces a co…
Optimal Control of Two-Player Systems with Output Feedback
Laurent Lessard, Sanjay Lall
In this article, we consider a fundamental decentralized optimal control problem, which we call the two-player problem. Two subsystems are interconnected in a nested information pa…
