摘要
为了实现异弹制导的全程鲁棒性,弥补变结构控制在滑模外不具有鲁棒性的不足,该文针对大机动目标,将有限时间区间全信息反馈H∞控制应用于滑模趋近运动段,用其解析解构造变结构趋近律,获得一种具有全程鲁棒性的H∞变结构导引律。分析了滑模运动的可达性和稳定性。仿真表明,与最优变结构导引和比例导引相比,该文设计的导引律制导精度更高,鲁棒性更强。
In order to realize the full-time robustness of the missile guidance and overcome the shortage of non-robust outside sliding-mode in the variable structure control,the full-information feedback H∞ control in limited time is applied to the approaching moving section of sliding-mode aimming at the target with big maneuvering.A variable structure closer tendency law is constructed by analytical result of full-information feedback H∞ control,and a new H∞ variable structure terminal guidance law with full-time robustness is achieved.The attainability and stability of sliding-mode motion is analyzed.Simulation results show that the new guidance law has higher robust and precision than the optimal variable structure guidance law and proportional navigation guidance law.
