摘要
随着对垂直起降飞行器研究的深入,飞行控制律的设计逐渐成为研究的重点。文中研究了小型复合式无人机飞行控制律的快速设计与验证方法。选定一种小型复合式无人机布局方案,设定飞行任务剖面,以飞行任务为导向设计飞行控制律算法,基于MATLAB/Simulink平台搭建飞行控制律模型,基于Amesim平台搭建飞机本体模型,集成控制律模型与飞机本体模型实现闭环联合仿真。通过建模与仿真手段,对飞行控制律设计算法进行快速验证,通过分析飞行性能仿真结果,实现对飞行控制律设计方案的快速迭代优化;同时,快速设计与验证方法在其他航空领域的控制系统与被控对象的联合仿真与分析上具备参考性。
With the in-dep th study of VTOL aircraft,the design of its flight control law has gradually become the focus of research.The rapid design and verification method of the flight control law of small compound UAV is studied.First,a small compound VTOL aircraft layout is proposed.Then,the mission profile is set up and the flight control law is designed based on it.The model of flight control law is built based on MATLAB/Simulink platform while the model of aircraft ontology is built based on Amesim platform.The flight control law algorithm is validated by modeling and simulation,and the fast iterative optimization of flight control law design scheme is realized by analyzing flight performance simulation results.Meantime,the fast design and verification solution can be used as a reference for the joint simulation and analysis of control systems and controlled objects in other aerospace fields.
