结合空间拦截的精确末制导问题，本文介绍一种对目标机动和参数摄动具有鲁棒性的自适应变结构制导律（ＡＶＳＧ）。在此基础上， 我们研究了一种智能自适应变结构制导方法（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率的抖动， 又可以保证制导精度， 仿真结果证明了ＩＡＶＳＧ 的有效性。
In this paper, we introduce an adaptive Variable Structure Guidance Law (AVSG) that is robust to the maneuver and parameter perturbation of the target. On this basis, we study an intelligent adaptive variable structure guidance method (IAVSG). This method estimates the intensity of the target normal acceleration precisely and adjusts the strength of the variable structure in the AVSG autonomously. In this way, the jitter of the visual angular rate can be eliminated and the guidance accuracy can be guaranteed. The simulation results prove that The effectiveness of IAVSG.
