The TITOP approach to multi-body modeling of flexible structures

The TITOP approach to multi-body modeling of flexible structures

SDTlib is based on the TITOP (Two-Input Two-Output Port) formalism. The TITOP model of a flexible body (a solar panel, for example) describes its dynamics independently of the rest of the system. By assembling TITOP models, we can build a model of a complex structure...

Precision pointing for an observation mission

Precision pointing for an observation mission

This R&D study, carried out under ESA contract in collaboration with Thalès Alenia Space, focused on optimizing the pointing performance of a generic observation mission. The system was fully modeled using SDTlib to perform a frequency analysis of the system and...

Robotic arm manipulation for on-orbit servicing

Robotic arm manipulation for on-orbit servicing

This R&D study, carried out in collaboration with ESA, focused on high-fidelity modeling of a robotic arm manipulation scenario, as part of an in-orbit service mission. SDTlib was used to model the service satellite and the customer, each with their own properties...

LFT modeling of uncertain systems

LFT modeling of uncertain systems

Context The term “uncertainty” refers to the necessary discrepancies between the mathematical model of a physical system, and the reality. Such uncertainties may degrade the stability or the performance of the system, and motivate for robustness considerations as of...
