自适应二阶滑模制导律
Self-Adaptive Second Order Sliding-Mode Guidance Law
摘要
Abstract
Conventional guidance laws designed based on Lyapunov theorems can not ensure the finite time convergence of guidance system. A novel second-order sliding-mode control approach with finite time convergence is presented by using sliding-mode control theory and is used in a maneuvering target interception scenario for a guidance law design. The first part of this guidance law features similar structure of proportional navigation with time-varying effective navigation ratio, so that the line-of-sight rate tends to zero. The extension part of this guidance law features line-of-sight ( LoS) shaping, finite time convergence of sliding mode surface and robustness to the variation of interception missile and target velocities. The simulations with nonlinear motion model are carried out for two typical target maneuvers. The results show that this guidance law can intercept the target effectively and can verify the above features.关键词
