In the future war, based on the important position of Multi-UAVs (Uninhabited Aerial Vehicle),mixed use Multi-UAVs and ground systems, will be the key to victory. This article selects the mathematical model of Multi-UAVs and its flight control research, to strengthen our military strength for future war, adapt to the requirements, and has a higher theoretical significance and practical value.Firstly,according to the characteristics of Multi-UAVs model,we establish the known quantity,controlled variable,and relevant coordinate system,use space flight dynamics theory and kinematics knowledge,then establish the position of leader under the wingman's coordinate system by appropriate disposal to keep the distance denoted by xr,y r,h r between leader and wingman under desired value. Secondly, the control law for Multi-UAVs were studied. By analyzing the characteristics of mathematical model, we get the error dynamic equation,after using Euler differentiation,the expression of the controller is educed by undetermined coefficient,then choose appropriate sampling period to reduce the error to minimum and achieve the control purpose. Finally, we set reasonable disturbances, simulate the conclusion by using Matlab to validate the feasibility of the controller and improve the control ability .
