Abstract��

Based on the harmonic balance principle, the saddle node,the period doubling bifurcation and chaos behavior are discussed in theory for a magnetic levitation control system. The approximate conditions, which determine the existence and onset zone of chaos in the system, are given. The results obtained may be helpful in design and control of the nonlinear magnetic levitation control system.

Keywords�� magnetic levitation   control system   chaos   bifurction   prediction
