マイコンを使った超臨界Heの状態制御

抄録

The development of a large scale refrigeration system is being stimulated by new superconducting techniques representated by a superconducting power cable and a magnet.
For the practical operation of such a large system, an automatic control system with a computer is required, because it can attain an effective and systematic operation.
For this reason, we examined and developed micro-computer control techniques for supercritical He generation, as a simplified control model of the refrigeration system.
The experimental results showed that the computer control system can attain fine controlability, even if the control element is only one magnetic valve, but a BASIK program language of micro-computer, which is convinient and generaly used, isn't enough one to control a more complicated system, because of its low calculating speed.
Then we conclude that a more effective program language for micro-computer must be developed to realize practical refrigeration control.
