| 摘要: |
| 倾斜转弯技术是高超声速滑翔飞行器控制的一个重要发展方向。针对高超声速滑翔飞行器倾斜转弯技术开展研究。以平衡滑翔弹道为参考弹道，分析了转弯半径、下降高度、倾侧角等参数之间的关系，提出在设计高超声速滑翔飞行器制导控制指令时，应综合考虑不同高度速度下的控制能力约束。根据奇异摄动理论将动力学系统的受控状态变量分为快变量和慢变量两部分，运用轨迹线性化方法设计了控制系统。仿真结果表明，设计的控制器具有良好的控制性能，但随着高度的增加，控制指令应结合实际控制能力，以完成对飞行器的姿态控制。 |

| Abstract: |
| Bank-to-turn (BTT) technology is an important development direction of control technology for hypersonic gliding vehicles. This research focuses on the control system of bank-to-turn for the hypersonic gliding vehicle. By taking the equilibrium gliding trajectory as the reference trajectory, it analyzed the relationship between turn radius, falling height, and bank angle. The analysis shows that when designing the guiding and control command, the flight conditions and the limitation of the control ability need to be considered. Then the dynamics were separated into fast and slow variables in terms of singular perturbation theory. Furthermore, the trajectory linearization control (TLC) method was applied to design the control system. Simulation results show that the controller is robust and the command should be adjusted with the flight conditions to control the vehicle efficiently. |
