Abstract

The rapid development of hypersonic vehicles has motivated the related research dramatically while the evasion of the hypersonic vehicles becomes one of the challenging issues. Different from the work based on the premise that the pursuers’ information is fully known, in this paper the evasion guidance for air-breathing hypersonic vehicles (AHVs) against unknown pursuer dynamics is studied. The gradient descent is employed for parameter estimation of the unknown dynamics of the pursuer. The energy-optimized evasion guidance algorithm is further developed by taking the acceleration constraint and energy optimization into consideration. Under the proposed algorithm, the system can deal with the unknown pursuer dynamics effectively and provide more practical guidance for the evasion process. The simulation results show that the proposed method can enable the AHV to achieve successful evasion.

Problem 1 Consider the PE game model given by Eq (6) with unknown pursuer dynamics given by Eq (9), the evasion strategy should be derived to minimize the energy consumption given by Eq (12), while the miss distance subject to Eq (10) and the control constraint subject to Eq (11)

Summary

Introduction

The rapid development of hypersonic vehicles has motivated the relate research dramatically [1, 2]. The advances of the hypersonic weapons drive the revolution of the abilities and strategies of pursuers. The hypersonic vehicles will be confronted with rigorous pursuit threat, and it is significant to carry out the research upon the evasion strategies of the hypersonic vehicles. As an emerging research area, the research on the evasion strategies of hypersonic vehicles is few. The few existing studies [3,4,5] are all aimed at known waypoints and no-fly zones, utilizing trajectory planning to achieve evasion. The research on pursuit-evasion (PE) games of hypersonic vehicles is almost blank.
