具有终端角约束的预设性能自适应滑模制导律
Adaptive Sliding Mode Guidance Law with Prescribed Performance and Terminal Angle Constraint
摘要
Abstract
To address the interception of maneuvering targets in three-dimensional space with terminal impact an-gle constraints and the issue of initial control input saturation,this paper proposes a prescribed performance-based a-daptive sliding mode guidance law capable of suppressing initial input saturation.Firstly,a three-dimensional relative motion model of the missile-target system is established.Then,an extended state observer is designed to estimate dis-turbances caused by target maneuvers,and a prescribed performance function with exponential convergence is intro-duced to constrain system error evolution.Based on this,a novel guidance law is developed by integrating prescribed performance control with adaptive sliding mode control to ensure that the line-of-sight(LOS)angle error remains within a predefined bound.Furthermore,to suppress initial control input saturation,a saturation constraint function is incor-porated into the guidance law design.Finally,comparative simulations under two target maneuvering scenarios are con-ducted.Results demonstrate that the proposed guidance law maintains the LOS angle error within 0.003° and limits the miss distance to less than 0.6 m,achieving high-precision interception while effectively avoiding initial input saturation.关键词
