针对如何控制在多路时空同步拦截弹中不同时间发射的弹丸在同一时间飞行到目标点进行起爆这一问题，使用Matlab／Simulink仿真技术对弹丸的外弹道运动过程进行了建模，并基于这一模型分析了多路时空同步拦截弹的工作原理，进而设计了相应算法对弹载阻尼环的开环时间进行计算；以双路系统模型为例，对该算法以及其计算结果进行了仿真验证。结果表明：该算法具有较精确的修正能力，通过选择合适开环时间，拉长了先发射弹丸的飞行时间，实现了时空同步起爆；算法基于Matlab／Simulink仿真建模技术，整个计算过程清晰直观，提高了计算精度。

Damping Ring Control Algorithm of the Mutiplex Time-Space Synchronization Interception Missile Based on Matlab/Simulink

To solve the problem of controlling the mutiplex time-space synchronization interception missiles which are launched at different time to reach the target at the same time and then to detonate,the model of the exterior trajectory moving process was established by Matlab/Simulink simulation technology. Basing on this model,the principle of the mutiplex time-space synchronization interception missiles was analyzed. And a corresponding algorithm for calculating the open-loop time of missile-borne damping ring was designed. At last,using the two-path model to simulate and verify the open-loop time which is chose-by the algorithm. The results show that the algorithm has accurate correction feasibility. By selecting suitable open-loop time,the two-path model prolongs the flight time of the first missile and then realizes time-space synchronization detonation. The algorithm based on Matlab/Simulink simulation and modeling technologies improves the calculation accuracy and the whole calculation process is clear and visual.
