Reinforcement Learning based Approximate Optimal Control of Nonlinear Systems using Carleman Linearization

By: J. Kar n, H. Bai * & A. Chakrabortty n 

topics (OpenAlex): Adaptive Dynamic Programming Control; Mechanical Circulatory Support Devices; Model Reduction and Neural Networks
TL;DR: This work develops a policy iteration-based model-free reinforcement learning (RL) control for nonlinear systems with single input that provides solutions close to the optimal control resulting from the model-based Carleman controllers. (via Semantic Scholar)

LSTM based Denial-of-Service Resiliency for Wide-Area Control of Power Systems

Kar, J., & Chakrabortty, A. (2021, October 18). 2021 IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe).

By: J. Kar n & A. Chakrabortty n 

topics (OpenAlex): Smart Grid Security and Resilience; Power System Optimization and Stability; Network Security and Intrusion Detection
TL;DR: A long short-term memory network (LSTM) is used and predicts the magnitudes of the corresponding missing states in a completely decentralized fashion using offline training and online data updates to resolve denial-of-Service (DoS) attacks in wide-area control loops of electric power systems.
