摘      要：A dynamic model of magnetic levitation control system with nonlinear magnetic force and feedback control is presented. Because of nonlinear magnetic force, the complex dynamic behavior will be shown in the system (codimension two bifurcation, Hopf bifurcation, heteroclinic bifurcation). By theoretical analysis, it is shown that the design of parameters has a close relation with the systems stability; the range of selected parameters is achieved when the controller system is stable, based on the condition of bifurcation parameters, bifurcation curve, bifurcation set and phase portraits. From the simulating of magnetic flywheel system, the complex dynamic behavior is shown, and the result is in correspondence with the theoretics. It is of great theoretic importance to improve design and stable control for the nonlinear magnetic levitation control system.
