一种自适应变结构制导律

为了使导弹制导系统具备良好的鲁棒性，本文提出用滑模变结构控制理论设计末端导引规律。结合时变系统的特点，本文提出并应用了滑模自适应趋近律这一概念。理论分析和数字仿真表明自适应变结构制导律具有优良的弹道性能和鲁棒性。另外，此制导律比较简单，便于应用。

AN ADAPTIVE VARIABLE STRUCTURE GUIDANCE LAW

Sliding-mode variable structure control is applied to design a guidance law so that the guidance law is robust to certain disturbances. Meanwhile, an adaptive trending-law of sliding-mode is presented for time-varing control systems and is used to derive the guidance law. Theoratical analysis and digital simulation results are provided to show that the adaptive variable structure guidance law is of good trajectory performance and robustness. Furthermore, this guidance law is easy to realize in engineering.
