In this paper mathematical model of the hybrid electromagnetic and permanent magnetic suspension system model is established, and sliding mode variable structure controller of the fuzzy approaching law is designed in the use of a sliding mode control strategy considering the open-loop instability, strongly nonlinear characteristics and etc. then mixed-maglev system has been effectively controlled. Simulation results show that the control method ensures the rapid of approaching movement, at the same time retains the robustness of sliding mode control system, effective in inhibiting the system chatter. |
