摘要
为了实现飞行仿真的人在回路控制和视景可视化,建立了飞机运动/动力数学模型和气动力/重力模型实时计算飞行参数和旋转四元数,并基于Matlab/Simulink环境构建仿真模块,利用V-realm Builder设计VRML三维虚拟现实空间用于视景可视化仿真,通过Simulink三维动画模块集将操纵设备、飞行控制模块与三维虚拟空间连成全仿真系统。仿真结果表明,仿真系统可实现飞行可视化仿真,视景界面逼真,能够准确、实时地输出飞行参数,可按照控制指令完成飞行动作,系统操纵性、通用性和可扩展性较好。
In order to create an flight visualization simulation system in man-in-the-loop, an aircraft motion/ dynamic and aerodynamic/gravity model was established to calculate flight parameters and expression of rotation quaternion in real time, and simulating module was designed based on Matlab/Simulink conditions. A 3D virtual reality space based on VRML was built up by V-realm Builder for simulating visualization. Operating device, flight control module and 3D virtual space were integrated into a complete simulating system by Simulink 3D Animation Blockset. Results of simulation indicate that the system can realize the flight visualization simulation with high fidelity of scene view, supply accurate and real-time flight parameter output, and implement flight under the control instruction. The system has good maneuverability, versatility and scalability.
