“…(i) In a lot of previous work [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], either the acceleration constraint is not taken into account, or the bang-bang control is directly adopted and the energy optimization is ignored. In contrast, the evasion strategy introduces the boundary value M(lower bound of miss distance for successful evasion) and combines the concept of SMD and NDG theory, so as to solve the energy optimization problem under the premise of acceleration constraints.…”

“…Therefore, the evasion command in this work is more practical and has wider applicability. (iii) In all the above-mentioned previous work [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], the evasion strategies are developed on the basis of the perfect information of the pursuers. In this paper, by introducing the gradient descent method, the dynamic information of the pursuer is estimated.…”

“…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. But the research on pursuit-evasion (PE) games of hypersonic vehicles is almost blank.…”

“…In the aforementioned studies [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], the evasion tasks are all achieved by maximizing the miss distance or the line-of-sight angle rate. However, for the purpose of energy optimization and the subsequent combat missions after the evasion, maximizing the miss distance may cause the undesired energy consumption and deviation from the original course, may not be the best choice.…”

And in the studies [22][23][24][25][26][27][28][29][30][31] of computational intelligence, the estimation of the uncertainty of pursuer dynamics is not addressed.…”

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.

Aiming at the penetration problem of high-speed vehicles against a modified proportional guidance interceptor, a three-dimensional mathematical model of attack–defense confrontation between the high-speed vehicle and the interceptor is established in this paper. The modified proportional navigation guidance law of the interceptor is included in the model, and control constraints, pitch angle velocity constraints, and dynamic delay are introduced. Then, the performance index of the optimal penetration of high-speed vehicles is established. Under the condition of considering the 180-degree BTT control, the analytical solutions of the optimal speed roll angle and the optimal overload of high-speed vehicles are obtained according to symmetric Hamilton principle. The simulation results show that the overload switching times of high-speed vehicles to achieve optimal penetration are N − 1, where N is the modified proportional guidance coefficient of the interceptor. When the maximum speed roll angle velocity is [60, 90] degrees per second, the penetration effect of high-speed vehicles is good. Finally, the optimal penetration guidance law proposed in this paper can achieve a miss distance of more than 5 m when the overload capacity ratio is 0.33.
