Abstract
We study a non-contact support and transportation of flexible steel plate by magnets. The magnetic support
system is essentially unstable because we get only attractive force by the magnet. Electromagnetic force is
controlled so as to keep the plate position at a fixed position. It is difficult to design the control system due to
the strong non-linearity of the force by the electromagnet and the flexibleness of the plate. We employ the
sliding mode control theory to get good quality control.
