Abstract:
In order to effectively control maglev-guideway coupling vibration, maglev-guideway coupling vibration system was simplified as electromagnet-elastic-track model. A full-state feedback optimum controller was developed. The guideway vibration information was introduced into the control system by state observer. A small-scale elastic-track magnetic levitation test rig was built using dSPACE. Compared with the traditional controller, the proposed control strategy can always keep the system stable, even the guideway is rather soft and no damping effect exists. Step response tested from the test rig indicates that the developed controller can stabilize the system in 0.3 s with a overshot of 4%. Analysis result shows that the control strategy isable to effectively restrain the coupling vibration. Moreover, it reduces the over-dependence of the system stability on the guideway beam properties based on satisfying maglev stability. 1 tab, 10 figs, 17 refs.
