Extending Flat Motion Planning to Non-flat Systems. Experiments on Aircraft Models Using Maple
François Ollivier
Aircraft models may be considered as flat if one neglects some terms associated to aerodynamics. Computational experiments in Maple show that in some cases a suitably designed feed…
On Singularities of Flat Affine Systems With States and Controls
Yirmeyahu J. Kaminski, Jean Lévine, François Ollivier
We study the set of intrinsic singularities of flat affine systems with controls and states using the notion of Lie-Bäcklund atlas, previously introduced by the authors.…
Automatic differentiation of hybrid models Illustrated by Diffedge Graphic Methodology. (Survey)
John Masse, Clara Masse, François Ollivier
We investigate the automatic differentiation of hybrid models, viz. models that may contain delays, logical tests and discontinuities or loops. We consider differentiation with res…
Intrinsic and Apparent Singularities in Flat Differential Systems
Y. J. Kaminski, J. Levine, F. Ollivier
In this paper, we study the singularities of locally flat systems, motivated by the solution, if it exists, of the global motion planning problem for such systems, in the spirit of…
A robust and passive method for geometric calibration of large arrays
Charles Vanwynsberghe, Pascal Challande, Jacques Marchal +2
This paper presents a complete strategy for the geometry estimation of large microphone arrays of arbitrary shape. Largeness is intended here in both number of microphones (hundred…
Nearfield Acoustic Holography using sparsity and compressive sampling principles
Gilles Chardon, Laurent Daudet, Antoine Peillot +3
Regularization of the inverse problem is a complex issue when using Near-field Acoustic Holography (NAH) techniques to identify the vibrating sources. This paper shows that, for co…
