Title (EN) POSITION CONTROL APPARATUS
(FR) APPAREIL DE COMMANDE DE POSITION
(JA) 位置制御装置
Abstract:
(EN) This position control apparatus is provided with: an oil temperature acquisition device which acquires information on an oil temperature of a hydraulic actuator; a position acquisition device which acquires a real value of an operation position of an object; a position controller which calculates an operation instruction value for a control valve of the hydraulic actuator by means of a closed loop control so as to decrease a difference between a target value and the real value of the operation position of the object; and a gain setting device which changes at least one gain of the closed loop control in a manner such that the sensitivity of the closed loop control is improved, as the oil temperature is lowered.
(FR) L'invention concerne un appareil de commande de position comprenant : un dispositif d'acquisition de température d'huile qui acquiert des informations sur une température d'huile d'un actionneur hydraulique; un dispositif d'acquisition de position qui acquiert une valeur réelle d'une position de fonctionnement d'un objet; un dispositif de commande de position qui calcule une valeur d'instruction de fonctionnement d'une soupape de commande de l'actionneur hydraulique au moyen d'une commande en boucle fermée de façon à réduire une différence entre une valeur cible et la valeur réelle de la position de fonctionnement de l'objet; et un dispositif de réglage de gain qui modifie au moins un gain de la commande en boucle fermée d'une manière telle que la sensibilité de la commande en boucle fermée est améliorée, à mesure que la température de l'huile baisse.
(JA) 位置制御装置は、油圧アクチュエータの油温に関する情報を取得する油温取得器と、対象物の動作位置の実値を取得する位置取得器と、前記対象物の動作位置の目標値と前記実値との偏差を減らすように閉ループ制御により油圧アクチュエータの制御弁に対する動作指令値を算出する位置制御器と、前記油温が低くなるにつれて、前記閉ループ制御の少なくとも1つのゲインを前記閉ループ制御の感度が上がる傾向に変化させるゲイン設定器と、を備える。
