Abstract:

Aiming at the trajectory optimization and guidance (TOG) of a hypersonic gliding vehicle considering under the condition of multi constrains, the methods of TOG are divided into off line TOG and on line TOG, and the prospect is brought forward. The mathematical models with stochastic disturbances of the TOG for the hypersonic gliding vehicle are first built. The off line TOG is summarized from two sides of determinacy and robustness, according to whether considering stochastic disturbances or not. The on line TOG is classified as reference guidance and predictive guidance, and the principle of the reference guidance is reference trajectory on line generation and reference trajectory tracking. Finally, it is pointed out that the future research of the TOG should be enhanced at the model, calculational efficiency, multitask, and high accuracy guidance and so on.
