| 中文摘要: |
| 针对高速高机动飞行器飞行过程中的禁飞区规避问题，提出一种新的飞行器横向制导算法，利用改进的扰动流体(interfered fluid dynamic system，IFDS)算法求取期望航向角，在飞行过程中实时更新航向角误差范围走廊，利用倾侧角反转逻辑控制飞行器横向运动，同时利用禁飞区绕飞判断准则和禁飞区威胁度排序两种策略提升禁飞区的规避效果。仿真实验证明该算法在复杂过程约束和终端约束条件下具有较好的禁飞区规避能力。 |
| 英文摘要: |
| A novel lateral guidance algorithm is proposed to address the no-fly zone avoidance problem during the flight of a high-speed, high-maneuverability aircraft. The algorithm employs an improved interfered fluid dynamic system(IFDS) to determine the desired heading angle and dynamically updates the heading angle error corridor in real time throughout the flight. The lateral motion of the vehicle is controlled using a bank angle reversal logic, while the avoidance performance is enhanced through two strategies: a no-fly zone circumvention judgment criterion and a threat-based ranking of no-fly zones. Simulation results demonstrate that the proposed algorithm effectively avoids no-fly zones while satisfying complex process constraints and terminal constraints. |
