前向拦截自适应滑模制导律

为拦截高速飞行目标，基于前向拦截的思想，给出了一种自适应滑模制导律．通过弹道的不断调整，置拦截导弹于具有较快飞行速度的目标前方预测弹道上，使得二者的飞行方向满足一种特定的几何关系．该制导律的推导考虑到了拦截导弹与目标的自动驾驶仪动态及其模型误差，且由于采用了自适应滑模的设计方法，不需要知道目标的加速度界和模型误差界．采...

Adaptive sliding-mode guidance law for head pursuit

Based on head pursuit consideration,a novel adaptive sliding-mode guidance law is presented for high-speed target interception.By adjusting the trajectory continuously,the interceptor is positioned ahead of the faster target to satisfy a specific geometry relation between the interceptor lead angle and the target flight direction relative to the line of sight(LoS).In this guidance law,the maneuvering dynamics of interceptor and target,and their model errors are considered.The boundary values of target acceleration and model errors are not required by use of adaptive sliding-mode design method.A realistic interceptor model is used in simulation and the results show that this guidance law can realize the head pursuit of high-speed targets and is feasibility.
