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。
Abstract
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.
