| 摘 要： | 在无人直升机控制律的设计过程中,需要对无人直升机进行建模,并对飞行中产生的一些不确定性因素进行仿真验证.目前,很多不确定性因素的描述是在非线性的环境中加入一些简单的扰动,然而能够确切地描述无人直升机动态特性的非线性模型在MATLAB中很难搭建.为此,文章从工程研究的角度,提出了在无人直升机线性模型组的基础上进行不确定性仿真验证的方法,从物理特性的角度描述无人直升机在悬停低速飞行时的对象特性不确定性,选择不确定或扰动因子;在MATLAB中建立了仿真模型,进行了无人直升机悬停低速段不确定性的验证.此方法简单、快速,并且能正确地反应无人直升机悬停低速段的不确定性,具有一定的工程意义.

| Abstract: | Uncertainties caused by modeling and flight of unmanned helicopter often simulated in the process of the control design. At present, many uncertainties are described by adding some easy little motion to the nonlinear model, which can＇t be accurately reflected in the MATLAB. For the way, this paper advanced a way to describe the uncertainties base on the complex plant characteristic in hover/low speed of the unmanned helicopter. The uncertainties simulation model was developed on MATLAB. This method could reflect the uncertainties in hover/low speed of unmanned helicopter easily, quickly and correctly. |
