Title
(EN) CASCADED ADAPTIVE FILTERS FOR ATTENUATING NOISE IN A FEEDBACK PATH OF A FLOW CONTROLLER
(FR) FILTRES ADAPTATIFS EN CASCADE POUR ATTÉNUER LE BRUIT DANS UNE CHAÎNE DE RÉACTION D'UN RÉGULATEUR DE DÉBIT
Abstract
(EN)
An electronics (100, 400) with cascaded adaptive filters for attenuating noise in a feedback path of a flow controller is provided. The electronics (100, 400) includes a signal processor (110, 410) configured to receive a flow signal (220a) from a flow sensor (220), the flow sensor (220) being configured to measure a flow rate of the pulsating flow, generate a noise reference signal (110b, 410b) from the flow signal (220a) and generate a flow rate signal (110a, 410a) using the noise reference signal (110b, 410b). The electronics (100, 400) also includes a controller (120) communicatively coupled to the signal processor (110), the controller (120) being configured to generate a flow rate control signal (120a) using the flow rate signal (110a, 410a), and a signal generator (130) communicatively coupled to the controller (120). The signal generator (130) is configured to receive the flow rate control signal (120a), generate a valve signal (130a) based on the flow rate control signal (120a), and provide the valve signal (130a) to a valve (210) to control the flow rate of the pulsating flow.

L’invention concerne une électronique (100, 400) dotée de filtres adaptatifs en cascade servant à atténuer le bruit dans une chaîne de réaction d’un régulateur de débit. L’électronique (100, 400) comprend un processeur de signaux (110, 410) conçu pour recevoir un signal d'écoulement (220a) provenant d'un capteur d'écoulement (220), le capteur d'écoulement (220) étant conçu pour mesurer un débit de l'écoulement pulsatoire, générer un signal de référence de bruit (110b, 410b) à partir du signal d'écoulement (220a) et générer un signal de débit (110a, 410a) au moyen du signal de référence de bruit (110b, 410b). L’électronique (100, 400) comprend également un régulateur (120) couplé au processeur de signaux (110) de manière à pouvoir communiquer, le régulateur (120) étant conçu pour générer un signal de régulation de débit (120a) au moyen du signal de débit (110a, 410a), et un générateur de signaux (130) couplé au régulateur (120) de manière à pouvoir communiquer. Le générateur de signaux (130) est conçu pour recevoir le signal de régulation de débit (120a), générer un signal de vanne (130a) sur la base du signal de régulation de débit (120a), et fournir le signal de vanne (130a) à une vanne (210) pour réguler le débit de l’écoulement pulsatoire.
