Stability Analysis of Nonlinear Magnetic Suspension System

LIU Heng-kun, CHANG Wen-sen (Engineering Research Center of Maglev, National University of Defense Technology, Changsha 410073, China)  
For analyzing stability of nonlinear magnetic suspension system, the basic model of magnetic suspension system was found based on electromagnet dynamics and voltage balance equation of the electromagnet coil. After the singularity of system was solved, then system matrix was computed according to linear outspread of system. The feedback quantity of additive current was controlled with PD, the control rule was imported into model system of equations to solve characteristic equation. The feedback coefficient of position and the range of the control parameter were gained with Louts criterion for the stability of nonlinear magnetic suspension system.
