Abstract
(EN)
Provided is a mechanistic model capable of diagnosing the status of elements possessed by a device for which precise positioning is required, and capable of diagnosing whether maintenance is required for these elements. Also provided is a mechanism control device using this mechanistic model. The mechanism control device, which positions an operation subject with high precision, and controls a control subject device configured from multiple elements, is equipped with: a model generation unit that generates a control subject model that simulates the control subject device, which is controlled in accordance with prescribed commands; an error detection unit that detects error between the control subject model and the control subject device; a model update unit that revises parameters for constructing the control subject model in accordance with the degree of error, thereby updating the control subject model generated by the model generation unit; a change determination unit that outputs status information indicating the degree to which a deviation value for the revised parameters has changed with respect to a threshold value; and control unit that displays the status information on a display device.

L'invention concerne un modèle mécaniste pouvant diagnostiquer l'état d'éléments compris dans un dispositif pour lesquels un positionnement précis est requis, et pouvant diagnostiquer si une maintenance est requise pour ces éléments. L'invention concerne aussi un dispositif de commande de mécanisme utilisant ce modèle mécaniste. Le dispositif de commande de mécanisme, lequel positionne un sujet d'opération avec une haute précision et commande un dispositif commandé constitué de plusieurs éléments, est équipé de : une unité de génération de modèle qui génère un modèle commandé qui simule le dispositif commandé, lequel est commandé en fonction d'instructions précises ; une unité de détection d'erreurs qui détecte l'erreur entre le modèle commandé et le dispositif commandé ; une unité d'actualisation de modèle qui révise des paramètres permettant de construire le modèle commandé en fonction du degré d'erreur, actualisant ainsi le modèle commandé généré par l'unité de génération de modèle ; une unité de détermination de changement qui transmet des informations d'état indiquant le degré auquel une valeur de déviation pour les paramètres révisés a changé par rapport à une valeur de seuil ; et une unité de commande qui affiche les informations d'état sur un dispositif d'affichage.
