涵道无人飞行器建模与线性鲁棒控制
首发时间:2014-01-17
摘要:本文介绍了一种基于马格努斯效应控制舵的涵道飞行器模型。模型所使用的控制舵包含了四个对称安装在飞行器尾部的回转轮。回转轮表面与涵道风扇喷射气流之间的相互作用产生了与回转轮转速成正比的气动升力,这样可以保证气动升力有足够宽的变化范围。最后,通过数值仿真,验证了整体飞行动力学模型及其控制方法的有效性。?

Modeling and Linear Robust Control for a Ducted Fan UAV
Abstract:A ducted fan aerial vehicle model using Magnus effect steering engine is proposed in this article. This model utilizes a steering engine that comprises four cylinders that are symmetrically installed at the aft inside the duct. Interaction between the spinning cylinder surface and the duct jet flow causes the aerodynamic lift proportional to angular velocity of the cylinder. Therefore, operating aerodynamic lift range is guaranteed to be sufficiently wide. The efficiency of the proposed method is confirmed via numerical simulations on integrated flight dynamics developed in this study.
Keywords: ducted fan aerial vehicle Magnus effect flight dynamics decoupling control
