高超声速再入轨迹跟踪控制的微分变换方法
Differential transformation-based trajectory tracking guidance scheme for hypersonic reentry vehicle
摘要
Abstract
Concentrating on the hypersonic reentry guidance under multiple constraints,a full-state nominal trajectory tracking guidance scheme was proposed by applying the differential transformation approach to the optimal feedback control.In the period of the online closed-loop guidance scheme based on the receding-horizon control,the nominal trajectory tracking problem was transformed into a state regulator problem of the associated linear time-varying system,and then into a two-point boundary value problem by utilizing the optimal control theory.The differential transformation approach was suggested for the optimal feedback control,avoiding the time-consuming and numerical instabilities of conventional methods.Numerical simulation results validate that the proposed guidance scheme is robust to state dispersions and model uncertainties,providing a reference for engineering design.关键词
