Four Reaction Wheels Management: Algorithms Trade-Off and Tuning Drivers for the PROBA-3 Mission

Autor: Aymeric Kron, Jean de Lafontaine, Amélie St-Amour

Publikováno v: IFAC Proceedings Volumes. 47:9685-9690

Reaction Wheels (RW) are common actuators for three-axis stabilized satellites. This paper deals with the management of a RW assembly where four or more skewed RW are used simultaneously. Four-wheel control is commonly used on spacecraft. This paper

PROBA-2 Attitude and Orbit Control System: In-Flight Results of Innovative GNC Functions

Autor: J. Naudet, Aymeric Kron, J. Côté, Stefano Santandrea, J. de Lafontaine

Publikováno v: IFAC Proceedings Volumes. 44:721-726

The PRoject for On-Board Autonomy (PROBA) is an ESA technology-demonstration program aimed at the in-orbit validation of autonomy-enabling space technologies. Following the success of PROBA-1, the PROBA-2 spacecraft was launched on 2 November 2009 an

Mu-analysis Based Verification and Validation of Autonomous Satellite Rendezvous Systems

Autor: Aymeric Kron, Jean Franois Hamel, Jean de Lafontaine, Alexandre Garus

Publikováno v: IFAC Proceedings Volumes. 43:327-332

This paper presents a Verification and Validation (VV) framework that integrates Linear Fractional Transformation (LFT) and mu-analysis with simulation based VV. This innovative VV framework is developed for the terminal phase of Mars Sample Return a

CONTROL OF MARS GUIDED ENTRY (PART I): ROBUST SELF-SCHEDULING MODAL CONTROL

Autor: Jean de Lafontaine, Aymeric Kron, José Torralba

Publikováno v: IFAC Proceedings Volumes. 40:575-580

Robust Modal Control theory can be extended in order to design Self-Scheduling controllers. In this paper, the technique is applied to the control of a Lander Module attitude dynamics during Mars atmospheric Entry. The extra degrees-of-freedom brough

CONTROL OF MARS GUIDED ENTRY (PART II): ROBUST NONLINEAR DYNAMICS INVERSION

Autor: Aymeric Kron, Jean de Lafontaine

Publikováno v: IFAC Proceedings Volumes. 40:581-586

This paper addresses the 6 degrees-of-freedom control of a Mars Lander Module during its aerodynamic entry phase. It focuses on Robust Nonlinear Dynamics Inversion (RDI) technique. On one hand, RDI is shown to be efficient for translation controller

ROBUST SYNTHESIS OF STATIC OUTPUT FEEDBACK CONTROLLER FOR MARS ENTRY

Autor: Aymeric Kron, Jean de Lafontaine, Catherine Le Peuvédic

Publikováno v: IFAC Proceedings Volumes. 39:655-660

This paper addresses the 6 degrees-of-freedom (DOF) control of a Mars Lander Module (LM) during its aerodynamic entry phase. It focuses on the robust synthesis of a static output feedback for the attitude dynamics. It presents a systematic way to des

The Generalized (μ,MU)-Iteration Illustrated by Flexible Aircraft Robust Control

Autor: Aymeric Kron, Jean de Lafontaine

Publikováno v: IFAC Proceedings Volumes. 37:701-706

Thanks to real-μ-analysis, the (μ,Mu)-iteration generalizes the discrete multi-model approach to a continuum of models, represented by LFT. The present paper proposes and explains how to generalize the (μ,Mu)-iteration to take into account robust
