摘要：

In this paper, a class of electromagnetic suspension system was investigated. Firstly, according to the Newtonian mechanics principle the forced state of the system was analyzed. The differential equation and the transfer function of the controlled system were deduced based on the system's law of electromagnetic induction. Then the PID controller and fuzzy controller were designed respectively. From the simulation results, it can be found that the system with fuzzy control can obtain fast response time, small overshoot and adjustment time, but the system has steady-state error and the system with PID control can eliminate the steady-state error, but with slow response time, and big overshoot and adjustment time. Finally, by combining the advantages of both methods a Bang-bang control method was proposed, in which Fuzzy controller operates when the deviation is large and PID controller operates when the deviation is small. Through the simulation results, we found that the method can satisfy the rapidity with no deviation.
