Gain-Only Neural Operator Approximators of PDE Backstepping Controllers

no code implementations28 Mar 2024 Rafael Vazquez, Miroslav Krstic

For the recently introduced deep learning-powered approach to PDE backstepping control, we present an advancement applicable across all the results developed thus far: approximating the control gain function only (a function of one variable), rather than the entire kernel function of the backstepping transformation (a function of two variables).

Towards a MATLAB Toolbox to compute backstepping kernels using the power series method

no code implementations24 Mar 2024 Xin Lin, Rafael Vazquez, Miroslav Krstic

Our first contribution is the development of initial steps towards a MATLAB toolbox dedicated to backstepping kernel computation.

MPC for Tracking applied to rendezvous with non-cooperative tumbling targets ensuring stability and feasibility

no code implementations16 Mar 2024 Jose Antonio Rebollo, Rafael Vazquez, Ignacio Alvarado, Daniel Limon

A Model Predictive Controller for Tracking is introduced for rendezvous with non-cooperative tumbling targets in active debris removal applications.

A hybrid dynamical system approach to the impulsive control of spacecraft rendezvous (extended version)

no code implementations6 Mar 2024 Alexandre Seuret, Rafael Vazquez, Luca Zaccarian

This paper introduces a hybrid dynamical system methodology for managing impulsive control in spacecraft rendezvous and proximity operations under the Hill-Clohessy-Wiltshire model.

Gain Scheduling with a Neural Operator for a Transport PDE with Nonlinear Recirculation

1 code implementation4 Jan 2024 Maxence Lamarque, Luke Bhan, Rafael Vazquez, Miroslav Krstic

The recently introduced neural operators (NO) can be trained to produce the gain functions, rapidly in real time, for each state value, without requiring a PDE solution.
