为提高脉冲修正弹药的末段修正控制效果,对其脉冲参数的优化设计问题进行研究。针对脉冲修正弹药脉冲离散控制的特点,建立了脉冲修正弹道模型,提出了一种脉冲控制策略,以弹目落点偏差最小为第一优化目标、以消耗脉冲总冲最小为次优目标,在一定约束条件下建立了脉冲参数优化数学模型,应用改进粒子群算法对脉冲参数进行了优化。数值计算结果表明,基于改进粒子群算法的脉冲参数优化设计数学模型具有较快的收敛性,利用该优化方法获得的脉冲参数,按照设计的修正控制策略,能够获得较佳的修正控制效果。

In order to improve terminal trajectory correction control effect of the impulse correction ammunition, the optimal design of the impulse parameters was studied. Aiming to the characteristics of impulse discrete control ,the impulse correction trajectory model is es- tablished and an impulse control strategy is proposed. The minimum falling point deflection between projectile and target and the minimum total impulse are considered as the first opti- mal and sub-optimal objective function respectively, an optimal design model of impulse pa- rameters is established under certain constraint conditions. The impulse parameters are opti- mized using modified Particle Swarm Optimization. The numerical results show that optimal design mathematical model of impulse parameters based on modified Particle Swarm Opti- mization has a faster convergence, a better correction control effect can be obtained through the use of impulse optimal parameters obtained by the optimal method and the correction control strategy designed in the paper.
