Abstract: Aiming at the control problem of aircraft cooperative formation based on leader follower structure, taking side slip turning aircraft as the research object, the integrated guidance and control (IGC) method is used to design the controller. Firstly, the relative motion coordinate system is defined in the inertial space, and the relative motion model is established. Combined with the dynamic model, the IGC model is obtained. Secondly, the formation controller is designed based on the sliding mode variable structure and neural network theory by using the backstepping method, and the stability of the control system is proved. Finally, the six degree of freedom numerical simulation is carried out under high speed condition, and the control performance of the IGC method is compared with that of the separate design method. The simulation results show that the IGC controller can construct and maintain the desired formation quickly and accurately, and it is superior to the separate design method.
