Abstract: Un dispositif de commande est décrit pour le contrôle de la position dun rotor soutenu par des paliers magnétiques. Un module de planification de trajectoire produit une position, une vitesse et une accélération demandées. Un observateur génère des valeurs de rétroaction sur la position et la vitesse à partir de mesures dune position du rotor et des intensités du courant dans les bobines délectro-aimants des paliers magnétiques. Un premier circuit de correction génère un premier signal selon la différence entre la position et la vitesse demandées et les valeurs de rétroaction sur la position et la vitesse. Une commande prédictive génère un deuxième signal selon les calculs de la position, de la vitesse et de laccélération demandées. Un additionneur additionne le premier et le deuxième signal et livre un troisième signal pour générer des signaux de commande de flux pour les électro-aimants. Un deuxième circuit de correction génère des signaux de commande de la tension pour les amplificateurs de puissance qui contrôle le courant circulant dans les bobines délectro-aimants selon la différence entre les signaux de commande de flux et les valeurs de flux de lobservateur.

Abstract: Methods and apparatus are provided for continuously powering tools downhole for extended periods of time, such as for the life of the producing well. Batteries may power the downhole tools, but traditionally, the batteries may last up to 2 years, and in some cases, up to 5 years may be reached with an optimized data sampling rate and power management scheme. After that time, operations may be halted temporarily for replacing the batteries. According to embodiments of the present invention, in contrast, rechargeable batteries 204 may be utilized downhole to provide power to operate the tools, and rather than halting operations and retrieving the rechargeable batteries 204 to the surface for recharging, reserve batteries 208/210 may be used for recharging the rechargeable batteries 204. In many cases, these well tools may be designed to operate for a long period of time (e.g., around 10-20 years), depending on the life of the producing well.
