| 摘要: |
| 采用固定配平攻角外形并进行滚转单通道控制是实现飞行器再入机动飞行最简单有效的方式之一,但是由于这种飞行器升力大小不可控,机动控制能力有限,确定合适的制导方法是实现其多约束条件下落点精确控制的关键。而现有解决方法难以同时满足多约束条件和较高落点精度要求。提出将轨迹优化和滚转制导律相结合的制导方法,利用高斯伪谱法实现标准轨迹的快速优化,满足多约束条件;利用滚转制导律实现这类飞行器对标准轨迹的跟踪,满足较高的落点精度。仿真结果显示所提出的制导方法能够有效解决固定配平飞行器的多约束精确制导问题。 |

| Abstract: |
| One of the most cost-effective designs for the maneuvering reentry vehicle is a simple lifting configuration with a fixed angle of attack employing a single roll control system. However, the limited maneuverability due to its uncontrollable magnitude of lifting force leads to the major obstacle to achieve the accurate steering with multiple constraints, so seeking a suitable guidance method is the key to overcome this obstacle. Existing ways are not available to solve this problem. This paper presents a new guidance method, which combined with the Gauss pseudospectral method (GPM) to satisfy the constraints, and the rolling guidance law to track the optimized trajectory accurately. The simulation result illustrates that, this method is effective to realize the precision guidance with multiple constraints for fixed-trim reentry vehicle. |
