Robust H2/H-infinity control under stochastic requirements: minimizing conditional value-at-risk instead of worst-case performance
Ervan Kassarian, Francesco Sanfedino, Daniel Alazard +1
Conventional robust H2/H-infinity control minimizes the worst-case performance, often leading to a conservative design driven by very rare parametric configurations. To reduce this…
Worst-case search in constrained uncertainty space for robust H-infinity synthesis
Ervan Kassarian, Francesco Sanfedino, Daniel Alazard +1
Standard linear H-infinity/H2 robust control and analysis tools operate on uncertain parameters assumed to vary independently within prescribed bounds. This paper extends their cap…
Non-linear dynamics of multibody systems: a system-based approach
Daniel Alazard, Francesco Sanfedino, Ervan Kassarian
This paper presents causal block-diagram models to represent the equations of motion of multi-body systems in a very compact and simple closed form. Both the forward dynamics (from…
Dynamics modelling and path optimization for the on-orbit assembly of large flexible structures using a multi-arm robot
Ricardo Rodrigues, Valentin Preda, Francesco Sanfedino +1
This paper presents a comprehensive methodology for modeling an on-orbit assembly mission scenario of a large flexible structure using a multi-arm robot. This methodology accounts…
