Control System Design Of An Electromagnet And Permanent Magnet Hybrid Suspension System

Magnetic levitation makes the life of the equipment greatly extend，due to thenon-contact to avoid friction and wear between the objects. For eliminating the needfor complex lubrication system and improving the operating conditions of theequipment，it has broad application prospects in terms of transportation, machinery,metallurgy, materials and so on. Therefore, this paper conducts in-depth study for themaglev system.First, this paper introduces prospects for development and research status of thehybrid suspension system. Second, through the analysis of electro-magnetic theory, thehybrid suspension system works are given. Third, by simulation, we design part of theelectromagnetic and permanent magnet hybrid suspension system, describe thehardware structure of the hybrid suspension system. Fourth， the mixed suspensionsystem of one-dimensional movement characteristics are studied， and theone-dimensional hybrid suspension system control programs and software design aregiven. Fifth，on the basis of the one-dimensional motion, the researchers mixedthree-dimensional motion characteristics of the suspension system are given，and athree-dimensional control scheme in hybrid suspension system and software design isgiven. Finally, according to the design of hardware and software, we set up anexperimental platform in the laboratory to verify the feasibility of the control systeminvolved.The experimental results show that the electromagnetic-permanent magnet hybridsuspension system established in this paper is effective, and the control system canachieve the stability rapid and accurate of the suspended three-dimensional motion ofobjects.
