摘　　要：为满足冲压发动机导弹实时解算动力航程边界的要求,建立了动力航程远边界的计算,充分考虑了冲压发动机与弹道之间的耦合特性和六自由度弹道仿真模型,设计了PID控制策略,采用黄金分割的搜索方法解算了远边界包络。利用切比雪夫多项式对包络线进行拟合获得边界函数,可为导弹实战使用时指挥决策提供参考。In order to satisfy the requirement of real-time solution of the dynamic range boundary of ramjet missile,the calculation model of the far boundary of the dynamic range was established accurately,and the coupling characteristics between ramjet and trajectory,and the six-degree-of-freedom trajectory simulation model was fully considered,and the PID control strategy was reasonably determined,and the far boundary envelope was solved by the golden section search method.The boundary function was obtained by fitting the envelope with Chebyshev polynomial,which can provide reference for the decision-making of the missile in actual combat.
