Scaling-Based Reciprocal Control Barrier Functions for Nonholonomic Mobile Robots
Tianyu Han, Bo Wang
This paper studies the construction of control barrier functions (CBFs) for force-controlled nonholonomic mobile robots subject to relative-degree-two safety constraints arising fr…
Nonholonomic directional pursuit and evasion: Global feedbacks
Bo Wang, Miroslav Krstic
In a recent paper by the second coauthor, directional pursuit-evasion for strictly forward-moving nonholonomic vehicles was solved "half-globally", namely under favorable initial l…
Universal Formula Families for Safe Stabilization of Single-Input Nonlinear Systems
Bo Wang, Miroslav Krstic
We develop an optimization-free framework for safe stabilization of single-input control-affine nonlinear systems with a given control Lyapunov function (CLF) and a given control b…
Further Results on Safety-Critical Stabilization of Force-Controlled Nonholonomic Mobile Robots
Bo Wang, Tianyu Han, Guangwei Wang
In this paper, we address the stabilization problem for force-controlled nonholonomic mobile robots under safety-critical constraints. We propose a continuous, time-invariant contr…
