A Modular Platooning and Vehicle Coordination Simulator for Research and Education
Kevin Jamsahar, Adrian Wiltz, Maria Charitidou +1
This work presents a modular, Python-based simulator that simplifies the evaluation of novel vehicle control and coordination algorithms in complex traffic scenarios while keeping…
Decoupled Design of Time-Varying Control Barrier Functions via Equivariances
Adrian Wiltz, Dimos V. Dimarogonas
This article presents a systematic method for designing time-varying Control Barrier Functions (CBF) composed of a time-invariant component and multiple time-dependent components,…
Generating and Optimizing Topologically Distinct Guesses for Mobile Manipulator Path Planning with Path Constraints
Rufus Cheuk Yin Wong, Mayank Sewlia, Adrian Wiltz +1
Optimal path planning is prone to convergence to local, rather than global, optima. This is often the case for mobile manipulators due to nonconvexities induced by obstacles, robot…
On Uniformly Time-Varying Control Barrier Functions
Adrian Wiltz, Dimos V. Dimarogonas
This paper investigates the design of a subclass of time-varying Control Barrier Functions (CBFs), specifically that of uniformly time-varying CBFs. Leveraging the fact that CBFs e…
Leveraging Equivariances and Symmetries in the Control Barrier Function Synthesis
Adrian Wiltz, Dimos V. Dimarogonas
The synthesis of Control Barrier Functions (CBFs) often involves demanding computations or a meticulous construction. However, structural properties of the system dynamics and cons…
Predictive Synthesis of Control Barrier Functions and its Application to Time-Varying Constraints
Adrian Wiltz, Dimos V. Dimarogonas
This paper presents a systematic method for synthesizing a Control Barrier Function (CBF) that encodes predictive information into a CBF. Unlike other methods, the synthesized CBF…
