Robust line-of-sight pointing control on-board a stratospheric balloon-borne platform
Ervan Kassarian, Francesco Sanfedino, Daniel Alazard +2
This paper addresses the lack of a general methodology for the controller synthesis of an optical instrument on-board a stratospheric balloon-borne platform, such as a telescope or…
Linear Fractional Transformation modeling of multibody dynamics around parameter-dependent equilibrium
Ervan Kassarian, Francesco Sanfedino, Daniel Alazard +2
This paper proposes a new Linear Fractional Transformation (LFT) modeling approach for uncertain Linear Parameter Varying (LPV) multibody systems with parameter-dependent equilibri…
Worst-Case Pointing Performance Analysis for Large Flexible Spacecraft
Ilham Courie, Francesco Sanfedino, Daniel Alazard
This paper presents a tool, PELIB, developed in MATLAB /SIMULINK environment to perform pointing performance analysis based on European pointing standards. PELIB is designed as an…
Integrated modelling of microvibrations induced by Solar Array Drive Mechanism for worst-case end-to-end analysis and robust disturbance estimation
Francesco Sanfedino, Daniel Alazard, Valentin Preda +1
Modern and future observation Space missions face increasingly more demanding pointing performance requirements. This is accompanied with the development of larger lightweight flex…
