一种高超声速飞行器的再入鲁棒输出反馈控制
A Robust Output Feedback Control Method for Reentry Hypersonic Vehicle
摘要
Abstract
Hypersonic vehicle X-38 has strong nonlinear time-varying coupling,uncertainty,many disturbance characteristics in re-entry phase.Aiming at this problem,a robust feedback linearization of uncertain nonlinear decoupling system was established,and the norm bounded uncertain linear system was established.The dynamic high gain observer was designed for decoupling uncertain systems,and the nonlinear term and uncertainty were dealt with effectively.The nonsmooth feedback controller was designed,and the tracking of system output with given accuracy was realized,and uncertainty estimation through the calculation of complex boundary was avoided to design robust controller.The simulation results show that the robust feedback linearization and nonsmooth control effectively guarantee the stability of the closed-loop system and inhibit the reentry uncertainty influence on control precision.关键词
