摘要
为了提高防空弹道修正弹拦截机动目标的能力,提出了一种弹载执行机构的控制方法.建立了防空弹道修正弹的质点弹道模型,根据弹道修正的基本原理,得到了脉冲控制的优化模型;针对脉冲控制的特点给出了脉冲点火控制策略;应用粒子群算法对脉冲控制指令进行了优化.通过引入脉冲能量消耗最小原则改进了适应度函数,搜索了控制指令的全局优化解.仿真结果表明,该方法使得防空弹药在拦截机动目标时具有较高的命中精度.
In order to improve the ability of anti-aircraft trajectory correction ammunition to intercept maneuvering targets,a control method of missile-borne actuator was proposed.The particle trajectory model was established.According to the basic principle of trajectory correction,the optimal model of impulsive control was obtained.The ignition pulse control strategy was given according to the characteristics of impulse control.The particle swarm optimization（PSO） was applied to optimizing the impulsive control instructions.By introducing the minimum consumption principle of pulse energy,the fitness function was improved.The overall optimal solutions of control instructions were searched.Simulation results show that this control method can make anti-aircraft ammunition gain high hit-precision to intercept maneuvering target.
