| 摘 要： | 为了减小最终脱靶量,研究了系统存在随机扰动时交班切换边界定位问题。首先建立了具有中制导和末制导的结构随机跳变系统模型,然后根据结构随机跳变系统理论进行系统概率分析,并在此基础上结合优化算法,得到最优的交班切换边界,使得当前脱靶量的数学期望和方差最小。最后,进行了某型导弹纵向俯仰通道仿真,验证了该方法的有效性。

| Abstract: | To decrease the missing distance,the handing-over bound between midcourse guidance and terminal guidance was studied when the system was disturbed by the stochastic noise.The system with stochastic jump structures can be modeled as two structures that are midcourse guidance mode and terminal guidance mode.Then,the probability of the system was analyzed based on the theory about the system with stochastic jump structures.Based on the optimal algorithm,the optimal handing-over bound that can make minimal expe... |
