摘要

A new predictive reentry guidance algorithm based on aerodynamic parameter online correction for hypersonic gliding vehicles was presented. The constraints of reentry flight were studied, and a basic program for controller design was given. The aerodynamic parameters' errors in the process of traditional target prediction were analyzed. With the new composite parameters for lift and drag, the method for aerodynamic parameter online correction was established. Online estimation and online correction were used to improve the adaptivity of the predictive reentry guidance. The longitudinal guidance law and lateral guidance law were then designed, and proved to work well with large aerodynamic disturbance. To test the capacity of the guidance method, the Monte Carlo simulation was used. The results indicate that the predictive guidance method with parameter online correction has high guidance precision and good robustness for the aerodynamic disturbance.
