CONTROL OF SEMI-ACTIVE SUSPENSION IN HIGH SPEED CAPSULE TRAIN BY USING HARDWARE-IN-THE-LOOP SIMULATION EXPERIMENT

摘要

Recently, as new generation of transportation system, the high speed capsule train is attracting attention in the world. The capsule train runs inside the tube whose pressure is under 0.001 atm. Since the amount of air is rare inside tube with this pressure, the air-resistance, the major obstacle to higher speed can be drastically reduced. Moreover, the capsule train is levitated from the tube surface by using electrodynamic suspension(EDS) method, which makes frictionless smooth running. Theoretically, the capsule train characterized by sub-vacuum tube and frictionless levitation could run with over 1,000km/h speed[1].
