Input-Constrained Spatiotemporal Tubes for Safe Navigation of Unknown Euler-Lagrange Systems in Dynamic Environments

Siddhartha Upadhyay, Ratnangshu Das, Pushpak Jagtap

Safe navigation in dynamic environments is challenging when system dynamics are unknown and actuator inputs are limited. Existing methods either rely on accurate models, require on…

Smooth Spatiotemporal Tube Synthesis for Prescribed-Time Reach-Avoid-Stay Control

Siddhartha Upadhyay, Ratnangshu Das, Pushpak Jagtap

In this work, we address the issue of controller synthesis for a control-affine nonlinear system to meet prescribed time reach-avoid-stay specifications. Our goal is to improve upo…
