In order to change the mode of performing filling in a rocket by manpower promotion, realize the automatic walking and stopping of the rocket body according to a specified speed and improve the reliability and the load adaptability of filling the rocket, the present invention provides an alternating current asynchronous motor driving control system for a rocket body support vehicle. The system comprises a frequency-converting control subsystem, a motor driving subsystem, a motor major loop interconnecting device and an encoder interconnecting device. The alternating current asynchronous motor driving control system changes the present condition that the rocket is pushed by manpower to assemble and return back a container to realize the purpose of the automatic filling of the rocket and improve the reliability and the load adaptability of the rocket filling.
