Reserch On Separation Stability And Formation Flying Of Multi-kill Vehicle

Along with the rapid development of missiles and large-scale deployment.Air and missile defense technology have attracted more and more attention from various countries, the technology of Multiple Kill Vehicle can effectively deal with the penetration form of ballistic release bait. It begs the question of true and false target recognition by the form of many to many. This paper mainly studies that the attitude stable controller design for the separation process of multiple kill vehicles and analysis the disturbance factors for separation process of multiple kill vehicle and the cooperative formation control problem of multiple kill vehicles.After command and control System release the launch command, the cabin of kill vehicle carry some kill vehicles flight to the book location and then release them. The kill vehicles need to track the separate initial attitude to complete separation process. Against these issues, this paper establishes the dynamics and kinematics model first. On this basis, designing the traditional attitude controller use nn accordance with the classical control theory, getting the linear model with the application of Small perturbations linearization method and the coefficient freezing method, then design the controller of three channels for the kill vehicles. On this basis, the design of the second-order sliding mode attitude controller and nonlinear dynamic inverse attitude controller has been established. And compare the characteristics of the three attitude controller via simulation.In order to optimize the separation process, the main factors affecting the separation process was simulated. The first consideration is the change before and after the kill vehicle launched rudder static stability, the anti-separation device initial disturbance angular velocity and killing time on the rudder surface Expand separation process stability. Since the pneumatic pressure center position after considering the effect of anti-static stability Expand the size of the response speed projectile. Finally, respectively, for the size and direction of the wind di sturbances affect multiple separation process to be simulated.Finally, in order to improve the effectiveness of anti-intercept more in the separation process ends with the secondary anti-anti-emperor in space flight formation. Therefore, the design of the main killer in the guidance law, primary and secondary anti-killing device uses a collar bomb and control strategy formation flying formations from the bomb, and designed more than killing the formation control model by simulation the formation control method the effectiveness of the policy.
