CONTROL DEVICE OR METHOD FOR PREVENTING LOOP OSCILLATION
(FR)
DISPOSITIF OU PROCÉDÉ DE COMMANDE CONÇUS POUR EMPÊCHER L'OSCILLATION EN BOUCLE
(ZH)
一种防止环路振荡的控制装置或方法
Abstract:
(EN)
The present invention relates to a control device and method for preventing loop oscillation, the device comprising: a regulation actuator, an analog-digital converter (ADC), a cost function detector, a loop filter, a control value regulator, and a digital-analog converter (DAC); the device also comprises: a first processor is used to receive a first parameter outputted by the cost function detector and perform first error modification according to the first parameter to obtain a second parameter, the second parameter being used to perform precision adjustment on the loop filter; the second parameter is outputted to the loop filter; the loop filter is used to receive the second parameter and perform filter operation according to the second parameter.
(FR)
La présente invention concerne un dispositif et un procédé de commande conçus pour empêcher l'oscillation en boucle, ledit dispositif comprenant : un actionneur de régulation, un convertisseur analogique-numérique (ADC), un détecteur à fonction de coût, un filtre à boucle, un régulateur de valeur de commande et un convertisseur numérique-analogique (DAC). Ce dispositif comporte également un premier processeur destiné à : recevoir un premier paramètre émis par le détecteur à fonction de coût ; réaliser une première modification d'erreur conformément au premier paramètre afin d'obtenir un second paramètre qui permet d'effectuer un réglage de précision sur le filtre à boucle ; émettre le second paramètre à destination du filtre à boucle, qui est prévu pour recevoir le second paramètre et effectuer une opération de filtrage conformément à ce second paramètre.
(ZH)
本发明涉及一种防止环路振荡的控制装置及方法,其中,所述装置包括:调节执行器、模数转换器(ADC)、代价函数检测器、环路滤波器、控制值调节器,数模转换器(DAC),所述装置还包括:第一处理器用于接收所述代价函数检测器输出的第一参数,根据所述第一参数进行第一误差修正得到第二参数,所述第二参数用于对所述环路滤波器执行精度调整;将所述第二参数输出给所述环路滤波器;环路滤波器用于接收所述第二参数,根据所述第二参数进行滤波运算。
