Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. .. addition to this simple volts per hertz control more advanced control methods such as vector control and direct torque control (DTC) exist. These methods adjust the motor voltage in such a way that the magnetic flux and mechanical torque of the motor can be precisely controlled. http://en.wikipedia.org/wiki/Variable-frequency_drive Vector control (also called Field Oriented Control, FOC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors by controlling the current fed to the machine. .. http://en.wikipedia.org/wiki/Vector_control_(motor) -------------------------------------------------- Note added at 10 heures (2009-09-18 07:38:32 GMT) -------------------------------------------------- Orientation control/encoder feedback control/vector control FR-A7AP A700 Orientation control Encoder feedback control Vector control: : This function is used with a position detector (encoder) installed to the spindle of a machine tool, etc. to allow a rotation shaft to be stopped at the specified position (oriented). This controls the inverter output frequency so that the motor speed is constant to the load variation by detecting the motor speed with the speed detector (encoder) to feed it back to the inverter under V/F control and advanced magnetic flux vector control. Vector control operation can be performed using a motor with encoder. http://en.wikipedia.org/wiki/Vector_control_(motor) -------------------------------------------------- Note added at 4 jours (2009-09-22 17:30:13 GMT) Post-grading -------------------------------------------------- Le mode Vectoriel permet un contrôle de type « sensorless vector » en boucle ouverte, ou vectoriel de flux en boucle fermée. Pour choisir, il suffit de sélectionner le nombre de points du codeur. http://literature.rockwellautomation.com/idc/groups/literatu... Les fonctionnalitées du L7 comprennent une commande vectorielle de flux en boucle ouverte ou boucle fermée et un système de démarrage simplifié. http://downloads.industrial.omron.de/IAB/Company info/OYMC/O... Le DIGIDRIVE SK est un variateur de fréquence, à contrôle vectoriel de flux en boucle ouverte, pour l’alimentation des moteurs asynchrones. http://www.leroy-somer.com/documentation_pdf/depliants_pdf/3... quelles sont les avantages et les inconvinients de la commande vectorielle d'une machine asynchrone ? .. Un variateur à contrôle vectoriel de flux sert à maitriser les oscillations du couple instantané et donc traiter les régimes transitoires ce qui n'est pas possible avec un variateur à u/f constant qui est, rappelons le, à contrôle scalaire (avec une aussi grande précision). http://www.electrotechnique-fr.com/variation-de-vitesse-frei...

Contrôle vectoriel de flux avec capteur http://89.18.164.63/manuals/Current Products/Controls/Varios... Je peux donc améliorer ma proposition : de « variable speed drive by flux control » à « variable speed drive by flux vector control ». |

The Stator phase CURRENTS are measured and converted into a corresponding complex (space) VECTOR. This CURRENT VECTOR is then transformed to a coordinate system rotating with the rotor of the machine. For this the rotor position has to be known. Thus at least speed measurement is required, the position can then be obtained by integrating the speed. Then the rotor FLUX linkage vector is estimated by multiplying the stator current vector with magnetizing inductance Lm and low-pass filtering the result with the rotor no-load time constant Lr/Rr, that is the ratio of the rotor inductance to rotor resistance http://en.wikipedia.org/wiki/Vector_control_(motor) |
