Abstract:
A signal correction arithmetic unit is provided in a control apparatus to control a magnetic force of a magnetic guide unit. The signal correction arithmetic unit differentiates detection signals of two gap sensors, and integrates and outputs a differential signal with a smallest absolute value. The output signal is used for magnetic control.
