Adversarial attacks in consensus-based multi-agent reinforcement learning
Martin Figura, Krishna Chaitanya Kosaraju, Vijay Gupta
Recently, many cooperative distributed multi-agent reinforcement learning (MARL) algorithms have been proposed in the literature. In this work, we study the effect of adversarial a…
Safety during Transient Response in Direct Current Microgrids using Control Barrier Functions
K. C. Kosaraju, S. Sivaranjani, V. Gupta
We consider the problem of guaranteeing that the transient voltages and currents stay within prescribed bounds in Direct Current (DC) microgrids, when the controller does not have…
Reinforcement Learning based Distributed Control of Dissipative Networked Systems
K. C. Kosaraju, S. Sivaranjani, W. Suttle +2
We consider the problem of designing distributed controllers to stabilize a class of networked systems, where each subsystem is dissipative and designs a reinforcement learning bas…
Distributed control of DC grids: integrating prosumers motives
Michele Cucuzzella, Thijs Bouman, Krishna Chaitanya Kosaraju +6
In this paper, a novel distributed control strategy addressing a (feasible) psycho-social-physical welfare problem in islanded Direct Current (DC) smart grids is proposed. Firstly,…
Voltage control of DC networks: robustness for unknown ZIP-loads
Michele Cucuzzella, Krishna Chaitanya Kosaraju, Jacquelien M. A. Scherpen
In this paper we propose a new passivity-based control technique for DC power networks comprising the so-called ZIP-loads, i.e., nonlinear loads with the parallel combination of un…
A novel passivity based controller for a piezoelectric beam
Krishna Chaitanya Kosaraju, Matthijs C. de Jong, Jacquelien M. A. Scherpen
This paper presents a new passivity property for distributed piezoelectric devices with integrable port-variables. We present two new control methodologies by exploiting the integr…
