摘要

摘要: 基于最优控制理论对威胁规避约束下战斗机引导控制方法进行研究.以空战态势参数为状态建立战斗机引导模型，以引导的快速性和经济性为性能指标，将战斗机引导问题建模为具有非线性状态约束和路径约束的最优控制问题，以武器攻击包线来描述目标火力威胁，并将威胁规避约束转化为引导过程的空战态势约束问题，为保证引导算法的实时性和有效性，引入滚动时域控制策略进行在线优化，并采用高斯伪谱法进行数值求解，基于典型作战场景进行仿真，结果表明所提出的引导控制方法能在保证引导安全性的前提下实现战斗机的最优引导.

Abstract: Guidance method with threat avoidance was researched based on optimal control theory. Guidance model was established based on situation parameter of air combat, and fighter guidance problem was constructed as an optimal control problem with nonlinear state restriction and path restriction. Weapon effective envelope was adopted for threat description. In order to assure the safety for fighter, threat avoidance restriction was converted into state restriction based on fire threat model for target, receding horizon control (RHC) strategy was introduced for real-time requirement in guide control, and Gauss pseudospectral method (GPM) was adopted in numerical calculation for precision requirement. Simulation was given based on typical operational scenario. Result shows the guidance method can reach the optimal guidance under safety condition.
