基于Simulink和FlightGear的飞行器可视化飞行仿真

Flight Visual Simulation Based on Simulink and FlightGear

飞行可视化仿真已成为工程实践中的必要步骤。利用Simulink和FlightGear仿真工作构建飞行可视化仿真模型已变得非常方便。建模中将工作重心集中到提高飞行器飞行模型精度的上,用S函数描述了飞行器的六自由度非线性模型,建立了包括舵机执行模块、导航控制模块的整体飞行仿真模型。示例表明,利用FlightGear模拟器可实现由simulink搭建的飞行视景仿真。

Flight visual simulation becomes a necessary step in the research gradually. It is convenient to build fight visual simulation model utilizing tools of Simulink and FlightGear. The focus of the research is on the point how to improve the flight precision of the model. A six degree of freedom nonlinear model of the aircraft is presented by S-function. The entire flight simulation model also includes actuator model and navigation and control model. The sample result shows that the FlightGear simulator could accomplish the flight visual simulation which is built in Simulink.
