Query: Robust Entry Vehicle Guidance with Sampling-Based Invariant Funnels   Managing uncertainty is a fundamental and critical issue in spacecraft entry
guidance. This paper presents a novel approach for uncertainty propagation
during entry, descent and landing that relies on a new sum-of-squares robust
verification technique. Unlike risk-based and probabilistic approaches, our
technique does not rely on any probabilistic assumptions. It uses a set-based
description to bound uncertainties and disturbances like vehicle and
atmospheric parameters and winds. The approach leverages a recently developed
sampling-based version of sum-of-squares programming to compute regions of
finite time invariance, commonly referred to as "invariant funnels". We apply
this approach to a three-degree-of-freedom entry vehicle model and test it
using a Mars Science Laboratory reference trajectory. We compute tight
approximations of robust invariant funnels that are guaranteed to reach a goal
region with increased landing accuracy while respecting realistic thermal
constraints.
