摘要
分析了真实飞机上惯性导航系统的基本原理,加速度计和陀螺仪工作原理及其测量输出参数。结合航空仿真技术发展和全任务飞行模拟器样机的任务需求,在MATLAB/SIMULINK平台上构建捷联惯性导航仿真模型;利用RT-LAB平台构建分布式飞行仿真系统,实现导航外部特性的半实物仿真;建立导航数据库,用于导航计算以确定飞机即时位置以及导航台自动调谐管理。将导航系统仿真模块作为整个系统仿真中的一个节点,实现与模拟机自动驾驶仪系统进行信息交互,从而实现自动导航。
In this paper,the basic principles of the actual navigation system are discussed,the working principles of the gyro and accelerometer and the output of measurement parameters are also analyzed.Considering current development of aviation simulation technology and practical request of the prototyping of full flight simulator,radio navigation models with the method of region navigation as well as strap-down inertial navigation models are made on MATLAB/SIMULINK platform intended for the simulation of outer characteristics of the navigation system.Through construction of a distributed flight simulation system based on RT-LAB platform,the outer characteristics of the navigation system are achieved with hardware-in-the-loop simulation.As one node in the whole simulation system,the navigation system plays a key role in communicating with other nodes.So that the system of Auto-navigation come true.
