Robust Peak-cost Constrained Reinforcement Learning
Shilpa Mukhopadhyay, Sourav Ganguly, Santosh Mohan Rajkumar +3
We study robust peak-cost constrained reinforcement learning (\ours), where the objective is to maximize expected reward while controlling the maximum cost encountered along a traj…
On Data-Driven Koopman Representations of Nonlinear Delay Differential Equations
Santosh Mohan Rajkumar, Dibyasri Barman, Kumar Vikram Singh +1
This work establishes a rigorous bridge between infinite-dimensional delay dynamics and finite-dimensional Koopman learning, with explicit and interpretable error guarantees. While…
Real-Time Linear MPC for Quadrotors on SE(3): An Analytical Koopman-based Realization
Santosh M. Rajkumar, Chengyu Yang, Yuliang Gu +3
This letter presents an analytical linear parameter-varying (LPV) representation of quadrotor dynamics utilizing Koopman theory, facilitating computationally efficient linear model…
Modeling and Analysis of Multiple Electrostatic Actuators on the Response of Vibrotactile Haptic Device
Santosh Mohan Rajkumar, Kumar Vikram Singh, Jeong-Hoi Koo
In this research, modeling and analysis of a beam-type touchscreen interface with multiple actuators is considered. As thin beams, a mechanical model of a touch screen system is de…
Online Delay Estimation and Adaptive Compensation in Wireless Networked System: An Embedded Control Design
