| 摘要: |
| 为实现平流层飞艇驻空阶段可控飞行，研究环境风场中横侧向轨迹跟踪的滑模控制方法。建立平流层飞艇驻空阶段动力学模型，将动力学方程解耦为纵向运动方程和横侧向运动方程，采用小扰动方法对动力学方程进行线性化；利用滑模控制对外部干扰强鲁棒的特性，设计横侧向轨迹跟踪的滑模控制器；以直线与圆组成的复合轨迹跟踪控制为例，对提出的轨迹控制方法进行仿真验证。仿真结果表明，所提基于滑模的轨迹跟踪控制方法鲁棒性好，在一定范围的风场扰动条件下，可以实现对指令轨迹的有效跟踪控制，响应特性好。 |

| Abstract: |
| In order to realize the controllable flight of stratospheric airships during floating, the sliding mode control for lateral trajectory tracking in wind field was researched. The dynamic models of the stratospheric airship during floating were established, and the models were linearized by using linear perturbation theory. The sliding mode controller for lateral trajectory tracking was designed. Considering that this method was insensitive to external perturbation, the trajectory tracking for linear formation and circular was simulated. Simulation results show that the robustness and response characteristic of the trajectory tracking method based on sliding mode control are both satisfactory, and the control accuracy is high in wind field. |
