Robust Time-Varying Control Barrier Functions with Sector-Bounded Nonlinearities
Felix Biertümpfel, Jungbae Chun, Peter Seiler
This paper presents a novel approach for ensuring safe operation of systems subject to input nonlinearities and time-varying safety constraints. We extend the time-varying barrier…

Time-Transformation-Based Analysis of Systems with Periodic Delay via Perturbative Expansion
Jungbae Chun, Sengiyumva Kisole, Matthew M. Peet +1
It is difficult to analyze the stability of systems with time-varying delays. One approach is to construct a time-transformation that converts the system into a form with a constan…

Parameterization of Seed Functions for Equivalent Representations of Time-Varying Delay Systems
Sengiyumva Kisole, Jungbae Chun, Peter Seiler +1
Abel's classic transformation shows that any well-posed system with time-varying delay is equivalent to a parameter-varying system with fixed delay. The existence of such a paramet…
