Mission-Centric Requirements Analysis of Model Predictive Control in Spacecraft Rendezvous and Proximity Operations
Nils Maier, Torbjørn Cunis, Tam W. Nguyen
Rendezvous and proximity operations (RPO) missions are commonly designed as a sequence of distinct phases each governed by its own sample time, constraint set, and cost structure,…
Worst-Case Probability Bounds for Finite-Horizon Safety under Moment Uncertainty
Renato Loureiro, Torbjørn Cunis
This paper addresses the problem of estimating upper bounds on the probability that a dynamical system will enter an undesirable region at some point within a finite time horizon.…
Input-to-state Stable Approximate Nonlinear Model Predictive Control with Realtime Feasibility
Jan Olucak, Torbjørn Cunis
In this paper, a computationally lightweight approximate robust nonlinear model predictive control (NMPC) law is proposed based on a pair of input-to-state control Lyapunov functio…
Sum-of-Squares Stability Verification on Manifolds with Applications in Spacecraft Attitude Control
Fabian Geyer, Friedrich Tuttas, Walter Fichter +1
In the context of spacecraft attitude control, parametrizations such as direction vectors or quaternions are often used to avoid singularities in the attitude representation. This,…
On the Practical Implementation of a Sequential Quadratic Programming Algorithm for Nonconvex Sum-of-squares Problems
Jan Olucak, Torbjørn Cunis
Sum-of-squares (SOS) optimization provides a computationally tractable framework for certifying polynomial nonnegativity. If the considered problem is convex, the SOS problem can b…
