Abstract

The controllability of double parallel magnetic suspension system with hybrid magnet is studied analytically. The most basic magnetic suspension system consists of a suspended object (floator), an electromagnet and a power amplifier. In double parallel magnetic suspension, two floators and electromagnets are controlled with a single power amplifier. Parallel magnetic suspension systems are classified according to the output of power amplifier and the connection of coils. The controllability of each type system has been already studied. When hybrid magnets are used for suspension, however, another classification must be considered, which is magnetic polarity. This paper discuss the controllability of double parallel magnetic suspension with different polarities.
