侧窗探测动能拦截器末段轨控方案
Orbit control scheme of the terminal course of side window detection kinetic kill vehicle
摘要
Abstract
In terms of the orbit control problem of the terminal course of side window detection kinetic kill vehicle( SWDKKV) , this article puts forward a new rail control scheme based on the variable structure control theory.First of all,an orbit control model under three dimensional space was established after considering the restraints of side window.Subsequently,a new type of sliding mode surface with variable structure was presented based on such features of side window detection kinetic kill vehicle as being only able to output constant switching thrust and having directional attitude constraints,and a bang⁃bang type of orbit control scheme suit⁃able for terminal intercept was designed.Lyapunov stability theory was adopted to strictly prove the stability of the proposed methods. In order to reduce jet consumption,a sliding dead zone was designed and the value range of parameters in sliding dead zone which can ensure hitting accuracy was studied. Simulation results show that the designed orbit control scheme can meet the accuracy re⁃quirements while sliding dead zone can reduce jet consumption.关键词
