摘　　要：为了从理论上寻求合理、有效的脉冲修正弹参数设计方法,提出对脉冲修正弹参数进行优化设计。选取脉冲发动机个数、单脉冲冲量大小、脉冲发动机轴向偏心距及尾翼导转角为优化设计变量,以脉冲发动机总冲最小为目标函数,并以某些脉冲参数、弹道参数等为约束条件,建立了脉冲修正弹参数优化模型。针对该模型的特点,在标准粒子群算法SPSO2011的基础上,提出了基于自适应罚函数且适于处理整数离散变量的改进粒子群算法。算例结果表明,该算法用于脉冲修正弹参数优化设计,可快速、可靠地获取最优解。To develop a reasonable and effective approach of parameters design for trajectory impulse-correction projectile, the optimal design of parameters was proposed. The number of impulses, the magnitude of single impulse, the impulse axial eccentricity and the fin oblique angle were selected as optimal design variables. Taking the total impulse as objective function and some other impulse and trajectory parameters as constraint conditions respectively, an optimal model for trajectory correction projectile was established. According to the property of this model, based on the standard particle swarm optimization （i. e., SPSO2011 ）, the modified particle swarm optimization（MPSO） with adaptive penalty function was proposed, which is also suitable for dealing with integral discrete variables. Simulation result indicates that the optimal solution can be obtained rapidly and reliably by applying MPSO to the parameters design of trajectory impulse-correction projectile.
