| 天线共形飞艇携带雷达在空中抵近侦察时，在指定空域进行盘旋飞行，其盘旋飞行性能直接影响搭载的雷达性能，为实现控制飞艇在盘旋飞行时的航线位置跟踪、姿态稳定，建立了含风场特性的通用六自由度非线性模型，并利用小扰动线性化方法将运动模型线性化。在此基础上，本文针对该飞行场景设计一种外环基于自适应PID+内环线性自抗扰法的双闭环盘旋飞行控制方法，并经过实际飞行验证，证明了控制方法的有效性，给出飞艇实际空中盘旋飞行姿态波动范围，为后续天线共形飞艇搭载雷达提供设计参考。 |

| Abstract: |
| When antenna conformal airships carry radar to perform reconnaissance in air, its performance of hovering flight directly affects the performance of radar on board. In order to control the airship’s airline position tracking and attitude stability during hovering flight, a general six?degree?of?freedom nonlinear model with wind field characteristics is established, and the motion model is linearized by using the small disturbance linearization method. On this basis, a method based on adaptive PID+LADRC for hovering flight is designed in this paper. Through the actual flight verification, the effectiveness of the control method has been demonstrated. The attitude fluctuation range is given when the airship makes hovering flight. The research is beneficial for the antenna conformal airships carrying radar. |
