The Study on the Virtual Prototype Modeling of MAGLEV Train

In view of the strong nonlinearity for suspension system of maglev train and the weak robustness problems of traditional PID controller with external disturbance, firstly, a mathematical model of the magnetic levitation control system has been established. A virtual prototype model of the maglev train has also been established by ADAMS. A self-tuning fuzzy adaptive PID controller which is suitable for the maglev suspension system has been designed by utilizing fuzzy rules to adapt PID parameters on-line. Simulation experiments by virtual prototype verified the anti-interference and strong robustness of the system whose control performances are superior to the traditional PID controllers to overcome interference in practical engineering.
