Benchmarking Empirical and Learning-Based Approaches for Feedforward Steering Control in Autonomous Racing
Georg Jank, Mattia Piccinini, Sebastian Wenk +3
Feedforward steering control is a key component of hierarchical control architectures for autonomous racing. The goal is to reduce steering corrections from the feedback controller…
Head-to-Head autonomous racing at the limits of handling in the A2RL challenge
Simon Hoffmann, Simon Sagmeister, Tobias Betz +17
Autonomous racing presents a complex challenge involving multi-agent interactions between vehicles operating at the limit of performance and dynamics. As such, it provides a valuab…
Control Lyapunov Functions for Optimality in Sontag-Type Control
Joscha F. Bongard, Boris Lohmann
Given a Control Lyapunov Function (CLF), Sontag's famous Formula provides a nonlinear state-feedback guaranteeing asymptotic stability of the setpoint. At the same time, a cost fun…
Dynamic Constraint Tightening for Nonlinear MPC for Autonomous Racing via Contraction Analysis
Joscha F. Bongard, Valentin L. Krieger, Boris Lohmann
This work develops a robust nonlinear Model Predictive Control (MPC) framework for path tracking in autonomous vehicles operating at the limits of handling utilizing a Control Cont…
Longitudinal Control for Autonomous Racing with Combustion Engine Vehicles
Phillip Pitschi, Simon Sagmeister, Sven Goblirsch +2
Usually, a controller for path- or trajectory tracking is employed in autonomous driving. Typically, these controllers generate high-level commands like longitudinal acceleration o…
