Hierarchical Frequency and Voltage Control using Prioritized Utilization of Inverter Based Resources
Rahul Chakraborty, Aranya Chakrabortty, Evangelos Farantatos +3
We propose a novel hierarchical frequency and voltage control design for multi-area power system integrated with inverter-based resources (IBRs). The design is based on the idea of…
Asynchronous Distributed Reinforcement Learning for LQR Control via Zeroth-Order Block Coordinate Descent
Gangshan Jing, He Bai, Jemin George +2
Recently introduced distributed zeroth-order optimization (ZOO) algorithms have shown their utility in distributed reinforcement learning (RL). Unfortunately, in the gradient estim…
Designing Optimal Key Lengths and Control Laws for Encrypted Control Systems based on Sample Identifying Complexity and Deciphering Time
Kaoru Teranishi, Tomonori Sadamoto, Aranya Chakrabortty +1
In the state-of-the-art literature on cryptography and control theory, there has been no systematic methodology of constructing cyber-physical systems that can achieve desired cont…
Learning Distributed Stabilizing Controllers for Multi-Agent Systems
Gangshan Jing, He Bai, Jemin George +2
We address the problem of model-free distributed stabilization of heterogeneous multi-agent systems using reinforcement learning (RL). Two algorithms are developed. The first algor…
A Robust Stackelberg Game for Cyber-Security Investment in Networked Control Systems
Pratishtha Shukla, Lu An, Aranya Chakrabortty +1
We present a resource-planning game for cyber-security of networked control systems (NCS). The NCS is assumed to be operating in closed-loop using a linear state-feedback $\mathcal…
Optimal Co-Designs of Communication and Control in Bandwidth-Constrained Cyber-Physical Systems
Nandini Negi, Aranya Chakrabortty
We address the problem of sparsity-promoting optimal control of cyber-physical systems (CPSs) in the presence of communication delays. The delays are categorized into two types - n…
