LEVITATION CONTROLLING METHOD FOR A MAGNETIC LEVITATION VEHICLE, CAPABLE OF EFFICIENTLY CORRECTING THE LEVITATION FORCE ACCORDING TO TEMPERATURE CHANGE

摘要

PURPOSE: A levitation controlling method for a magnetic levitation vehicle is provided to reduce the sensitivity of a levitation system to the temperature of electromagnet coil and an excessive air gap by adding a magnetic flux to a levitation control algorithm.;CONSTITUTION: In a levitation controlling method for a magnetic levitation vehicle, a voltage is supplied to an electromagnetic coil for levitation(S10). The electromagnetic coil levitates a coil-wound magnet from a guide rail. Magnetic flux variation of the electromagnetic coil is measured according to the temperature change of the coil(S20). The voltage supplied to the electromagnetic coil is controlled to offset the change of the magnetic flux variation with reference a memory(S30).;COPYRIGHT KIPO 2012
