Abstract：Compared with the conventional aerodynamic control,the aerodynamic resistance and heating can be reduced if a flight vehicle is controlled by adopting mass moving control under condition of flying at a high speed.By so doing the maneuverability and agility of vehcles can be enhanced greatly to provide quali-fications for the improvement of the control efficiency and precision of the vehicles.In this paper,taking an interception missile flying at the last stage as a control target,based on the coupled nonlinear system of the missile constructed math model,in view of the influefnce of the aerodynamic parameters and that of the in-determinate factors of the collectivity parameters,and the chattering of the system in the control process , a quick terminal sliding mode control system is developed via backstepping and integral.Through the sta-bility analysis and the simulation of the masses locomotion,the results show that the method is effective and feasible.
