| 摘 要： | 针对小型涵道风扇无人机本体不稳定特性，设计增稳控制律并通过仿真进行了验证。利用软件CATIA建立三维模型，并制作出实体模型。对模型进行受力分析，建立涵道风扇无人机六自由度动力学模型。在所建模型基础上，设计增稳控制律，包括姿态控制律及轨迹控制律。建立非线性仿真模型，通过Matlab／Simulink仿真对所设计的控制律有效性进行了验证。仿真结果表明，所设计的控制律达到了增加涵道风扇无人机稳定性的目的。

| Abstract: | Aiming at the instability of a small scale ducted- fan UAV, CAS is designed and tested through simulation. First and foremost, a three- dimensional model is established with the three- dimensional mod- eling software CATIA. The physical model has also been built. The forces and moments of the UAV are analyzed and the 6- D dynamic model of ducted fan UAV is established. Based on the model developed, CAS is designed, including attitude control law and path tracking control law. Nonlinear simulating- sys- tem of the control law is established. The effectiveness of the CAS is also tested by Matlab/Simulink simu- lation. The simulation result shows that the CAS can meet the need to augment stability. |
