| Abstract |
Based on the decoupled control method of attractive-normal and thrust forces in a single-sided linear
induction motor (SLIM), a compact combined-levitation-and-propulsion SLIM Maglev vehicle can be
realized without any additional levitation magnet. In a Maglev system, if the distance between two pillars
of the guideway is long compared with the vehicle length, a vibration of the guideway is one of the most
important problems to be solved. This paper presents a combined-levitation-and-propulsion control to
suppress the guideway vibration in Maglev vehicle realized by SLIM only. For very difficult levitation
control combined with propulsion, much more accurate airgap length has been estimated from measured
one by sensor and short-primary end effects on attractive levitation force has been taken into account.
Experimental results has shown that the vehicle can be stably propelled and levitated simultaneously on
the flexible guideway. |
