Robust Nonlinear Trajectory Tracking Control for Autonomous Racing on Three-Dimensional Tracks
Joscha F. Bongard, Georg Jank, Simon Sagmeister +1
We propose a robust nonlinear model predictive control (MPC) scheme for trajectory-tracking control of autonomous vehicles at the limits of handling on non-planar road surfaces. We…
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…
