Reentry Control and Performance Evaluation Method for Hypersonic Vehicle
摘要
Abstract
A new robust control strategy is proposed for the reentry attitude tracking of hypersonic vehicle in the presence of model uncertainty and external disturbances.Firstly,a super twisting sliding mode controller based on backstepping method is designed for the dynamics of attitude motion,and the finite time stability of closed-loop system is analyzed.On this basis,a novel performance evaluation index system for the reentry control system of Hypersonic Vehicle is established.Then,a evaluation method based on AHP (analytic hierarchy process) method and entropy evaluation method is proposed.Finally,Matlab simulation is combined with the proposed evaluation method to verify the effectiveness and the robustness of the control strategy.关键词
