Stabilisation d'un actionneur électrohydraulique en considérant les dynamiques des distributeurs
Bibliographic record
Abstract
RESUME -Cet article est dédié à la stabilisation d'un actionneur électrohydraulique en tenant compte, dans la synthèse de la loi de commande, de la dynamique des distributeurs. Le comportement des actionneurs à fluide sous pression peuvent êtres décrits par des équations différentielles non linéaires qui sont seulement continues (c'est-à-dire non dérivables). Nous proposons dans cet article une extension de certains résultats de la littérature sur la stabilisation d'une classe de systèmes non linéaires lorsque le champ de vecteurs définissant le système est seulement continu. Il est à noter que la loi de commande proposée est donnée explicitement et elle est appliquée à la stabilisation d'un vérin hydraulique en tenant compte de la dynamique des distributeurs et ceci sans effectuer aucune linéarisation du modèle.ABSTRACT -This paper is devoted to the stabilization of an electrohydraulic actuator taking into account the dynamics of the valves.The behaviour of actuators in fluid power systems can be described by non linear differential equations which are only continuous (i.e.not of class C 1 ).We propose in this paper an extension of some results on the stabilization of a class of non linear systems when the vector fields are only continuous.Notice that the obtained control law is given explicitely and is applied to the stabilization of an hydraulic cylinder taking into account the dynamics of the valves and without any kind of linearization.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
