摘 要：This paper proposes a novel method for the integrated guidance and control（IGC） of glider in dive and pull-up *** main objective is robust and adaptive tracking for flight path angle（FPA）.Firstly,the integrated guidance and autopilot nonlinear model is built based on the IGC with a second order rudder *** the back-stepping Xi adaptive control is implemented to deal with the aerodynamics coefficient uncertainties,control surface uncertainties and unmatched time-varying disturbances in IGC *** the autopilot,a back-stepping sliding mode control is designed to track the control input of IGC,and a nonlinear differentiator is used to avoid direct differential of the control *** a series of 6-DOF numerical simulations,it’s shown that the proposed scheme successfully cancels out the uncertainties and disturbances in tracking two kinds of FPA *** contribution of this paper lies in the application and determination of nonlinear integrated design of guidance and control system for hypersonic glide.
