摘　　要：空战接敌过程中战斗机进行机动导致控制量剧烈变化,既影响飞机性能的发挥也不利于飞行员的操作。针对引导策略的优化问题,提出了一种带容许偏差的近似最优接敌策略。首先,建立了三自由度的运动模型,并提出了角度偏差的计算思路;其次,建立了离散的非线性规划模型,并分析了约束条件及目标函数;然后,介绍了滚动时域控制并给出了控制过程的数值解法;最后,设计一个前半球攻击的实例,将比例引导策略与带容许偏差的近似最优策略进行比较。结果表明:后者的控制量在最大稳定步长、均值、标准差方面均更优,能减轻飞行员的操作压力,是一种有效的接敌策略。The controllers fluctuate wildly because of the fighter maneuvering in air combat engagement process, which has effect on fighter＇s performance and pilot＇s controlling. According to the optimal problem of guidance strategy, an approximate optimum of engagement maneuvering strategy with allowable deviation is proposed. Firstly, three degree of freedom motion model is built. At the same time, the solution steps of angle deviation are put forward. Secondly, the discrete nonlinear programming model is built and the restriction and objective function are analyzed. After that, it introduces receding horizon control and proposes a numerical solution of controlling process. At last, an example of forward hemisphere attack is designed to comparing proportional navigation strategy with the designed engagement maneuvering strategy. The result shows that the latter＇s controllers fluctuate more smoothly. Therefore, It is an effective strategy which can lighter pilot＇s operation pressure.
