Title
(EN) METHOD AND APPARATUS FOR AUTO-TUNING A CONTROLLER FOR A DC-AC CONVERTER
(FR) PROCÉDÉ ET APPAREIL DE RÉGLAGE AUTOMATIQUE D'UN RÉGULATEUR POUR UN CONVERTISSEUR CC-CA
Abstract
(EN) A system (200) including a proportional -integral-derivative (PID) controller (201), a modified relay feedback test (MRFT) block (202), a memory block (211), a biasing block (213), a dq0-to-abc transformation block (210), a switch (207) configured to selectively couple output signal of the biasing block or the PID controller output signal to the input of the dq0-to-abc transformation block (210), a three phase digital pulse width modulator (208), electronic switches (203), a voltage sensor (206) configured to measure the output of each voltage of the three phases on the load and produce voltage data signals (Voa, Vob, Voc), and an abc-to-dq0 transformation block (209) having an input being a representative of the phase voltages on the load, and producing an output being a representative of these voltages in the dq0 format.
(FR) La présente invention concerne un système (200) comprenant un régulateur proportionnel-intégral-dérivé (PID) (201), un bloc d'essai de rétroaction de relais modifié (MRFT) (202), un bloc mémoire (211), un bloc de polarisation (213), un bloc de transformation dq0-abc (210), un commutateur (207) configuré pour coupler sélectivement un signal de sortie du bloc de polarisation ou le signal de sortie de régulateur PID à l'entrée du bloc de transformation dq0-abc (210), un modulateur de largeur d'impulsion numérique triphasé (208), des commutateurs électroniques (203), un capteur de tension (206) configuré pour mesurer la sortie de chaque tension des trois phases sur la charge et produire des signaux de données de tension (Voa, Vob, Voc), et un bloc de transformation abc-dq0 (209) ayant une entrée qui représente les tensions de phase sur la charge, et produisant une sortie qui représente ces tensions au format dq0.
