From Non-Rigid to Rigid: Safe Acquisition of Rigid Communication Graphs under Limited Sensing
Saharsh, S. Saharsh, Vedhas Talnikar +1
Communication graph rigidity is a fundamental requirement in many multi robot formation control approaches. However, ensuring and maintaining a rigid communication topology becomes…
Learning Spatiotemporal Tubes for Full Class of Signal Temporal Logic Tasks for Control of Unknown Systems under Input Constraints
Ahan Basu, Ratnangshu Das, Soumyodipta Nath +2
This paper presents a Spatiotemporal Tube (STT)-based control framework for general unknown nonlinear Euler-Lagrange (EL) systems subject to input constraints, with the objective o…
Learning from Demonstration via Spatiotemporal Tubes for Unknown Euler-Lagrange Systems
Ratnangshu Das, Puneeth Shankar, Varuni Buereddy +2
We present STT-LfD, a unified Learning from Demonstration (LfD) framework that integrates motion learning with control for unknown Euler-Lagrange systems. Unlike traditional decoup…
Temporal Reach-Avoid-Stay Control for Differential Drive Systems via Spatiotemporal Tubes
Ratnangshu Das, Ahan Basu, Christos Verginis +1
This paper presents a computationally lightweight and robust control framework for differential-drive mobile robots with dynamic uncertainties and external disturbances, guaranteei…
Prescribed Performance Control of Unknown Euler-Lagrange Systems Under Input Constraints
Ratnangshu Das, Pushpak Jagtap
In this paper, we present a prescribed performance control framework for trajectory tracking in Euler-Lagrange systems with unknown dynamics and prescribed input constraints. The p…
Spatiotemporal Tubes for Probabilistic Temporal Reach-Avoid-Stay Task in Uncertain Dynamic Environment
Siddhartha Upadhyay, Ratnangshu Das, Pushpak Jagtap
In this work, we extend the Spatiotemporal Tube (STT) framework to address Probabilistic Temporal Reach-Avoid-Stay (PrT-RAS) tasks in dynamic environments with uncertain obstacles.…
