Abstract: With the inevitable deviations of the wheel radius, motor parameters and adhesion features in the parallel driving chains of the wheel-rail antenna, torque asynchronization and system failure may occur frequently. In this paper, a parallel “two-drag-four” driving strategy is proposed, in which the rolling velocity of antenna pedestal is closed-loop controlled with two individual converters driving four motors. The dynamic model of the pedestal rotation and the wheel-rail adhesion feature are firstly established, and the “two-drag-four” model is built in Simulink based on the flux oriented vector control of single motor. The simulation results indicate that, the “two-drag-four” strategy has stronger control redundancy contrast to “one-drag-four” against the sectional adhesion features deviation in the rotation cycle, and the dynamic tracking capacity could be guaranteed with speed and torque synchronization.
