Modeling and analysis of a flexible spinning Euler-Bernoulli beam with centrifugal stiffening and softening: A Linear Fractional Representation approach with application to spinning spacecraft

no code implementations31 Jan 2024 Ricardo Rodrigues, Daniel Alazard, Francesco Sanfedino, Tommaso Mauriello, Paolo Iannelli

The derivation of a linear fractional representation (LFR) model for a flexible, spinning and uniform Euler-Bernoulli beam is accomplished using the {Lagrange} technique, fully capturing the centrifugal force generated by the spinning motion and accounting for its dependence on the angular velocity.

Modeling, robust control synthesis and worst-case analysis for an on-orbit servicing mission with large flexible spacecraft

no code implementations16 Jun 2022 Ricardo Rodrigues, Valentin Preda, Francesco Sanfedino, Daniel Alazard

This paper outlines a complete methodology for modeling an on-orbit servicing mission scenario and designing a feedback control system for the attitude dynamics that is guaranteed to robustly meet pointing requirements, despite model uncertainties as well as large inertia and flexibility changes throughout the mission scenario.
