Type of article: Article

Summary

CONVENTIONAL CONTROL SYSTEMS DEVELOPED SO FAR FOR LONG DISTANCE COOLING CHANNELS, ARE NOT YET CAPABLE OF LOCAL-TEMPERATURE CONTROL, LOCAL-PRESSURE CONTROL OR SEQUENTIAL CONTROL, SINCE THERMODYNAMIC PROPERTIES OF SUPERCRITICAL HELIUM SHOW AN ORDER OF MAGNITUDE CHANGE AND STRONG NONLINEARITY FOR APPLIED PRESSURE AND TEMPERATURE OF CABLES AND MAGNETS. IN THIS PAPER, A NEW TEMPERATURE CONTROL METHOD FOR LONG DISTANCE COOLING CHANNELS USING A MICROCOMPUTER IS PROPOSED. THIS METHOD IS CONTROLLABLE WITHOUT THE NECESSITY TO CONSIDER THE THERMODYNAMIC PROPERTIES OF SUPERCRITICAL HELIUM, BECAUSE A TYPE OF LEARNING CONTROL METHOD IS ADOPTED.
