Saturation-Aware Robust Trajectory Optimization for Reusable Launch Vehicles via Differentiable Physics

arXiv:2607.09736v1 Announce Type: new Abstract: The high-angle-of-attack flip maneuver of reusable launch vehicles presents significant challenges for robust trajectory optimization due to the combined effects of highly nonlinear dynamics, aerodynamic uncertainties, and actuator saturation. This paper presents a differentiable physics framework for saturation-aware robust trajectory optimization. At its core, a Differentiable Particle Tube Control (DPTC) scheme is developed to optimize uncertain...
