| Abstract: | This paper quantitatively analyzes the selection of the control parameters G 1 and G 2 by means of the numerical simulations for dynamic behavior of a maglev vehicle with two degrees of freedom on flexible guideway, to provide a selecting style of control parameters G 1 and G 2 . Moreover, the effect of the control parameters G 1 and G 2 and the designed parameters(e.g., maglev body mass M 5, moving velocity v and guideway length L) on the dynamic behavior of the magnetic levitated system is discussed and the characters of dynamic deformation of flexible guideway are analyzed for different guideway structure. |
