Study On Some Issues For Electric Control System Of Object's Magnetic Suspension

In recent years, EML technology find its wide application transportation, metallurgy, machinery, spaceflight and other fields, but the technology of electromagnetic suspension system for many aspect still is developing. We accept a part of that work. Before this research,the relevant personnel has designed and studied on devices and feasibility of electromagnetic - magnetic suspension system.On this basis, the article will research and design electrical control of suspended solid'position of electromagnetic - magnetic suspension system .First, this article introduces some important content about electromagnetic - magnetic suspension system what the relevant personnel has designed and studied ,and use it as the design basis for this.Secondly, on this basis reviewing the relevant knowledge that can use in this design, this paper analyzes the electrical control system and put forward the design scheme.Then, this thesis introduces main hardware which was used in an electrical control system of electromagnetic - magnetic suspension system.Finally, this study researches electric control way of electromagnetic - magnetic suspension system in depth, then designs PID electrical control system and FUZZY PID electrical control system. This thesis applies the PID electrical control system In the practical operation, making the electromagnetic - magnetic suspension system carry out preliminary. I summarize the insufficiency of the whole system and predict the develop direction of next step.
