Abstract

This paper presents a unified framework for addressing the stability analysis of the hovering condition for a multirotor vehicle. By linearization about a trim condition, a decoupled model made of four dynamic modes is derived. A set of stability derivatives is obtained and the effect on natural dynamic stability of design parameters such as arm dihedral and rotor tilt angles is analyzed. A numerical test case is finally discussed in support of the proposed approach.

摘要

本文提出了用于解决多旋翼飞行器悬停条件稳定性分析的统一框架。通过对修整条件进行线性化，推导了由四个动态模式组成的解耦模型。获得了一组稳定性导数，并分析了诸如臂二面角和转子倾斜角等设计参数对自然动态稳定性的影响。最后讨论了一个数字测试用例，以支持所提出的方法。
