Line Deviation Control of Cooperative Maneuvering Penetration,Guidance and Control Integration
Aiming at the problem of cruise missile terminal-guided multi-missile maneuvering penetration,a coordinated maneuvering penetration,guidance and control integration method based on line deviation control is proposed,which not only realizes the attack time consistency of the group of missiles under the bounded constraints of rudder deviation angle,but also improves the capability of single-missile penetrate through the trajectory maneuvering.Firstly,the maneuver penetration trajectory is decomposed into a virtual guidance trajectory and a relative maneuver trajectory,and a virtual guidance model and a guidance and control integration model for the relative maneuver trajectory are established.Secondly,a time-coordinated guidance law is designed for the virtual guidance trajectories of the follower;and thirdly,the line deviation command and the guidance and control integration algorithm are designed reasonably to realize the helical maneuver penetration trajectory of a group of missiles.The command filter and extended state observer(ESO)are adopted to realize the state constraints and interference estimation,and rigorously proves the stability of the closed-loop system based on Lyapunov stability theorem.Finally,the effectiveness and robustness of the designed method are verified by numerical simulations and Monte Carlo experiments.
