【摘要】 脉冲力控制技术具有响应速度快,易实现机动等优点,常用的脉冲控制策略有固定时刻修正和实时探测修正,但基于固定阈值的实时探测修正的弹道修正效果较差。本文在建立弹体质点外弹道模型的基础之上,提出一种基于自适应阈值的实时探测修正策略,即一种使用随时间动态变化的修正阈值代替固定阈值的控制策略。最后进行仿真验证基于自适应阈值的实时探测修正优于固定时刻修正和基于固定阈值的实时探测修正。更多还原

【Abstract】 Pulse force control technology has the advantages of fast response and easy maneuvering. The commonly used pulse control strategies include fixed time correction and real-time detection correction, but the trajectory correction effect of real-time detection correction based on fixed threshold is poor. In this paper, based on the establishment of the external ballistic model of the projectile, a real-time detection and correction strategy based on adaptive threshold is proposed, that is, a control strategy that uses the dynamic change of the modified threshold with time instead of the fixed threshold. Finally, the simulation results show that the real-time detection correction based on adaptive threshold is better than the fixed time correction and the real-time detection correction based on fixed threshold.更多还原
