摘要
为便于对飞行器建模和控制等理论技术进行演示和验证,采用软件工程的概念设计并实现了一种通用的研究型可视化飞行仿真平台.首先,基于面向对象的思想设计了仿真平台的总体结构和各个主要功能模块,建立了飞行器运动/动力和飞行控制模块的数学模型,并为其设计了模式化的接口,使平台可适用于多飞行器多控制策略下的飞行仿真.为获得较高的仿真真实度,建立了风切变、紊流的飞行干扰模型.然后,在各模块设计的基础上,基于.Net框架和Direct3D绘图编程接口实现了飞行仿真平台.最后,在PID飞控规律下,通过跟踪矩形航迹进行仿真实验.结果表明,该平台具有良好的可操纵性和逼真度,实时输出的飞行参数较为准确、全面,符合预期.
In order to facilitate demonstrating and validating theoretical technology of aircraft modeling and controlling,a general research visualized flight simulation platform is designed on the basis of software engineering concepts.Firstly,the overall structure and main functional modules are designed based on object-oriented idea.In order to simulate many types of aircraft in various control laws on the platform,mathematical models for flight movement and flight controlling are established,and modeling interfaces are designed for each main module.Flight disturbing models for wind shear and turbulent flow are established to obtain higher fidelity of the simulation.Then,the flight simulation platform is realized based on.Net framework and Direct3D.Finally,simulation verification is carried out by following rectangular track in the laws of proportional-integral-derivative（PID） flight controlling.The experimental results show that the platform has good maneuverability and fidelity,and the flight data from the real time output are accurate and entire,which fits in with the expectations.
