上制御装置。 In a magnetic levitation control device having a compensation circuit that calculates a deviation from a set gap of a levitation object based on an input gap sensor signal and outputs a control signal for an excitation current of a levitation magnet according to this deviation, the compensation circuit , magnetic levitation characterized by having a control characteristic in which when the deviation from the set gap is small, the rate of change in the control signal due to gap variation is small, and as the deviation increases, the rate of change in the control signal due to gap variation increases. Control device.
