Abstract：In this project， the motion reconstruction of the space cooperation vehicles is realized by using a moving base system. The following researches are carried out base on the control problem of the motion reconstruction： searching a method for the cross-scale stable operation and stability augmentation of a moving base， designing a new type of steering and driving mechanism， trajectory tracking control and coordinated control of the moving base. The research also tries to simulate the operating characteristic of the space cooperation vehicles in a microgravity environment through the stability analysis and control of the base system， which provides theory foundation and experiment data for the stability analysis and control of space motion body. In 2013， a great progress has been achieved in the modeling of the non-holonomic system， trajectory tracking control， cross-scale stable operation and stability augmentation， coordinated control， and the construction of the experiment platform of the moving base. Some rewards are also achieved and the achievements are highly evaluated by the domestic and foreign scholars. The expected goals are successfully accomplished. Since the project started， 44 papers are published totally including 26 papers indexed by SCI， and 15 papers indexed by EI. Three patents are applied. In addition， 10 papers are about to be published or have been accepted. and most papers are published in well-known international journal or conference， such as IEEE Transaction on Control Systems Technology， IEEE Transactions on Industrial Electronics， Journal Differential Equations， FUZZY sets and system， Physics Letters A， Journal of Dynamics and Differential Equations， International Journal of Control， Fuzzy sets and systems， AcTa Actomatica Sinica and so on.

Key Words：Modeling； Trajectory tracking control； Stable operation and stability augmentation； Coordinated control strategy； Construction of the experiment platform
