摘　　要：为解决常规控制策略难以高效修正中末制导交班误差的问题,提出了一种新的控制策略。首先建立了直/气复合控制系统的数学模型,然后分析了反临拦截器常见的轨控直接力开启策略,并通过仿真比较,选出控制效果最佳的轨控策略。在此基础上,结合反临拦截器的工作需求,提出了基于零控脱靶量和过载偏差的轨控策略,并将其与已有的轨控策略进行比较。仿真结果表明,新的控制策略可以在保证命中精度的前提下,燃料消耗降低40%以上,更利于打击位置偏差更大的目标。In order to solve the problem that conventional control strategy is difficult to effectively correct the handover error of midcourse and terminal guidance,a new control strategy is proposed in this paper.Firstly,the mathematical model of compound control system with lateral thrust and aerodynamic is established,then the common orbital control strategies of near space target interceptors are analyzed,and through simulation comparison,the orbital control strate⁃gies with the best control performance is selected.On this basis,combined with the work requirements of near space target interceptors,an orbital control strategy based on zero-effort miss and overload error is proposed.The simulation results show that the new control strategy can reduce fuel consumption over 40%on the premise of ensuring hitting pre⁃cision,which is more conducive to hitting targets with larger position error.
