摘　　要：研究了飞行器精密制导方式之一复合制导律优化问题。首先给出了采用串联式复合制导飞行器的几种中、末优化制导律，利用文中所述改进的最速下降优化方法，选择了中制导采用最佳预测制导律，末制导段采用改进的比例导引律的比例系数Ｋ的最优值，最后结合实例进行了仿真计算。In this paper,the optimization of guidance law in compound guidance hasbeen studied,which is one of the vehicle precise guidance. First, some kind of middle andfinal segment optimized laws are given when serial compound guidance is used. By using so─called fastest fall method,the value K of proportion coefficient has been got whichoptimizes both the middle segment and final segment of guidance, when the middle segmentis with the best prediction and the final is with pure proportion law. Finally,simulation withapractical example has been made.
