摘要
关于炸弹精确制导优化控制问题,是根据精确制导炸弹的飞行特点,要求精确打击目标。为了修正运动中的偏差,设计了制导炸弹的中制导规律,以实现对目标的精确打击的控制系统,提出了以预测落点作为反馈控制量的预测落点导引律,将制导炸弹有效导引向目标的任务,且保证落点脱靶量小。为提高制导律性能,进一步设计了比例微分积分形式的修正预测落点导引律,并进行了六自由度仿真及打靶试验。仿真结果表明,修正预测落点导引律生成的制导参数变化平稳、分布合理,可使制导炸弹保持很好的弹道性能,从而保证对目标实施精确打击,为精确制导设计提供了依据。
With the flight characteristics of the precision guided bomb,the midcourse guidance law is studied in the paper to precision striking against the targets.In this paper,a guidance law based on the impact point predication is developed,which is successful guiding the bomb to the target with small miss distance.To improve the law's performance,another impact point predication guidance law(IPPGL) with PID feedback is designed.The 6-DOF motion model and simulation using Monte Carlo method are simulated.The results show that guidance command form the IPPGL is changed rather slowly and reasonable.
