Abstract:

To improve the ability of the PLA rocket force to strike precisely the slow moving targets at sea and the penetration ability of the anti-ship ballistic missiles, the integrated cooperative guidance and control (ICGC) problem of the anti-ship ballistic missiles structured by “leader-follower” is discussed. First of all, the ICGC problem is refined as a coordinate consistency algorithm design problem for a class of high order nonlinear multi-agent system with disturbance by transforming the mathematical model. After that, based on the consistency theory and extended state observer (ESO) theory, the distributed consistency ICGC law is designed for the “leader-follower” multi-anti-ship ballistic missile system in the structure of the dynamic surface control (DSC). Then, the stability and convergence property of the closed-loop system is proven and analyzed strictly; and the convergence condition is got. The ICGC law can guarantee the slave missiles coordinate consistently in position and velocity and approach to the desired spacial structure. This makes the attack angles of the slave missiles are nearly the same as the leader missile. Finally, a series of simulations and comparisons are demonstrated to illustrate the effectiveness and advantages of the proposed ICGC law.
