Magnetic suspension is classified and can be divided into superconductive magnetic suspension and electromagnetic magnetic suspension from the material which produces lift force. It is a very plicated problem to control the magnetism suspension system. The focal point that this text studies is that these two kinds of magnetic suspension demonstrate the design about question of controlling of the experimental provision. Superconductive magnetic suspension is to utilize the superconductor in superconductive state to upbraid magnetic force principles. To suspend object superconductor,so superconductive control focal point of magnetic suspension drop on the superconductor superconductive magnetic suspension. This text is from remend that the using basically of superconductive magnetic suspension is started with, introduce the basic physical property of the superconductor , then the control method , course and principle to introduce superconductive magnetic suspension deeply progressively. Compared with superconductive magnetic suspension, the application that electromagnetic magnetic suspension is much more extensive , because the realization course that electromagnetic magnetic suspension is much simpler. Magnetic suspension that electromagnetic magnetic suspension and can be divided into the magnetic suspension which use the electromagnet and quoted the non electric magnetic magnet (tombarthite permanent magnet, ordinary magnet ,etc. ). But because the electromagnet is more convenient and utilizes controlling, it is more extensive to use the magnetic suspension of the electromagnet. The research in electromagnetic magnetic suspension of this text is to proceed with a instance , analyse that according to the principle of electromagnet type magnetic suspension , thus study electromagnetic type magnetic suspension control method , course and principle further. At the end of this text, I utilize knowledge studied in the university, bine the resea
