Exact-Time Safety Recovery using Time-Varying Control Barrier Functions with Optimal Barrier Tracking
Yingqing Chen, Christos G. Cassandras, Wei Xiao +1
This paper is motivated by controllers developed for autonomous vehicles which occasionally result into conditions where safety is no longer guaranteed. We develop an exact-time sa…
Finite-time Convergent Control Barrier Functions with Feasibility Guarantees
Anni Li, Yingqing Chen, Christos G. Cassandras +1
This paper studies the problem of finite-time convergence to a prescribed safe set for nonlinear systems whose initial states violate the safety constraints. Existing Control Lyapu…
Robust Dynamic Pricing and Admission Control with Fairness Guarantees
Yingqing Chen, Anni Li, Christos G. Cassandras +3
Dynamic pricing is commonly used to regulate congestion in shared service systems. This paper is motivated by the fact that in the presence of users with varying price sensitivity…
Robust Taylor-Lagrange Control for Safety-Critical Systems
Wei Xiao, Christos Cassandras, Anni Li
Solving safety-critical control problem has widely adopted the Control Barrier Function (CBF) method. However, the existence of a CBF is only a sufficient condition for system safe…
