Abstract:
In order to investigate the propulsion control strategy and achieve a high static and dynamic performance of high speed maglev transportation, the speciality of position measuring of MAGLEV Vehicle was taken into consideration, the construction of position measuring system was introduced and the time delay during position signal transmitted was discussed. According to the principle of vector control and automation control, the transfer function and state equations of control system are deduced. Detail analyses of the influence of the timedelay on the static and dynamic performance of the propulsion control system were given. It can be concluded that a long delay time results in the losing of thrust, destruction of decoupling ability and reduction of operation bandwidth.
