摘要
无人机数学模型的研究和建立是其飞行实时仿真系统和研究其飞行控制律设计的基础,针对某型无人机进行飞机运动方程的建模与仿真研究,建立了飞机六自由度非线性飞行运动学和动力学模型,并在Matlab/SIMULINK软件环境下建立数字仿真模型和线性化模型。飞行仿真模型采用了模块化的设计结构,具有一定的通用性。
The mathematical model of the unmanned aerial vehicle is a fundamental part of the real-time flight simulation system and flight control laws design. A six degrees-of-freedom non-linear model of an aircraft is first developed based on the flight characteristic data of the unmanned aerial vehicle. This model comprises of two main parts which are the formulation of equations of motion and the computation of forces and moments. The emulation model of block diagram and the linearized model are both developed in the Matlab/SIMULINK environment, and these models have modular structure and certain commonalities.
