Fast Online Reinforcement Learning Control using State-Space Dimensionality Reduction
Tomonori Sadamoto, Aranya Chakrabortty, Jun-ichi Imura
In this paper, we propose a fast reinforcement learning (RL) control algorithm that enables online control of large-scale networked dynamic systems. RL is an effective way of desig…
Game-Theoretic Mixed Control with Sparsity Constraint for Multi-agent Networked Control Systems
Feier Lian, Aranya Chakrabortty, Alexandra Duel-Hallen
Multi-agent networked control systems (NCSs) are often subject to model uncertainty and are limited by large communication cost, associated with feedback of data between the system…
Sparsity-Promoting Optimal Control of Cyber-Physical Systems over Shared Communication Networks
Nandini Negi, Aranya Chakrabortty
Recent years have seen several new directions in the design of sparse control of cyber-physical systems (CPSs) driven by the objective of reducing communication cost. One common as…
A New Cyber-Secure Countermeasure for LTI systems under DoS attacks
Nilanjan Roy Chowdhury, Nandini Negi, Aranya Chakrabortty
This paper presents a new counter-measure to mitigate denial-of-service cyber-attacks in linear time-invariant (LTI) systems. We first design a sparse linear quadratic regulator (L…
Modeling and Quantifying the Impact of Wind Power Penetration on Power System Coherency
Sayak Mukherjee, Aranya Chakrabortty, Saman Babaei
This paper presents a mathematical analysis of how wind generation impacts the coherency property of power systems. Coherency arises from time-scale separation in the dynamics of s…
