一种自适应双滑模制导律研究

根据导弹-目标追逃问题的相对运动学关系,基于反演思想设计了双滑模变结构导引律,运用自适应方法实现对制导系统参数不确定性和目标机动的估计,该导引律能够保证导弹在击中运动目标的同时满足期望落角;然后运用Lyapunov稳定性理论分析了该制导律进入平衡状态的充分条件.仿真结果表明了该设计方法的有效性.

A Self-Adaptive Double Sliding Mode Guidance Law

According to the relative movement relation of pursuit-evasion problem of missile against target,a double sliding mode guidance law based on backstepping is proposed.The guidance law can guarantee the missile to hit the moving target at a desirable azimuth.A sufficient condition of entering to the state is analyzed by using Lyapunov Theory of Stability.A self-adaptive method is used to estimate the unknown information during the flight,such as target acceleration and system parameters,then,the robustness to...
