空间拦截智能自适应变结构导引规律研究

结合空间拦截的精确末制导问题，本文介绍了一种对目标机动和参数摄动具有鲁棒性的自适应结构制导律（ＡＶＳＧ）。在此基础上，我们研究了一种智能自适应变结构制方法（ＩＡＶＳＧ）。此方法精略地估计出目标法向加速度的强度，并以此为依据自主地调整ＡＶＳＧ中变结构项的强度，这样，既可以消除视线角速度的抖动，又可以保证制导精度，仿真结果证明了ＩＡＶＳＧ的有效性。

INTELLIGENT ADAPTIVE VARIABLE STRUCTURE GUIDANCE FOR SPACE INTERCEPTION

An adaptive variable structure guidance law (AVSG) which is robust to target maneuver and parameter perturbations is proposed for the precise guidance of space interceptor.Based on the AVSG,we study an intelligent AVSG method (IAVSG),which autonomously adjusts the magnitude of variable structure term in the AVSG according to the magnitude of an approximetely estimated target maneuver.The IAVSG is albe to eliminate chattering and ensure guidance accuracy.Simulation results show the effectiveness of the presented method.
