Magnetic levitation technology has been largely developed and applied to modern industry in recent years. Possessing the qualities of noiselessness, low power wastage, and safety, it has prevailed the field for people's attention and interests in developing and researching. The maglev system is controllable and observable when we take the current of the coil as the system output, so we can replace the gap sensor by an observer. Such a system is called sele-sensing maglev system. This thesis also discusses and demonstrates that the reaching law control (a mew approach of VSS conrol) can well stabilie the system. In addition, the analog circuit, constructing based on the reaching lw approach and the reduced-order observer algorithm, is applied to the magnetic model in practice.
