动态飞行模拟器停机运动控制方法

Shutdown Movement Control for Dynamic Flight Simulator

在战斗机飞行模拟器优化设计中,为了在地面对飞行员进行持续性高过载训练,提出设计动态飞行模拟器(DFS)。在DFS系统在运行过程中,基于安全上的考虑,可采用不同的停机策略。为了减少停机时对人员及设备的损伤,需要对DFS停机过程运动控制方式展开研究。在分析DFS工作原理及停机模式分类基础上,建立了不同停机模式下的运动控制数学模型。在MATLAB中对不同停机模式进行数值仿真,验证数学模型的有效性,研究停机时DFS运动规律,仿真结果验证了所建立模型的有效性,结果表明针对不同停机模式下建立的飞行模拟器数学模型能够有效控制动态停机。

In order to take high sustained G- load training for pilot on the ground, the dynamic flight simulator （DFS） is more and more urgent for our air force. During DFS operation, based on safety consideration, there are dif- ferent shutdown strategies. In order to reduce damage to personnel and equipment during shutdown, a movement con- trol method of DFS shutdown is presented. Firstly, DFS shutdown mode and handle way are analyzed, based on anal- ysis of DFS components and the principle of the operation, a mathematic model of different shutdown modes is estab- lished. In order to test the capability of the mathematic model, different shutdown numeric modes are simulated by u- sing the model on Matlab, the regularity of DFS motion during shutdown is also investigated. Simulation results vali- date that the model is effective and also indicate that the mathematic model of different shutdown modes can effective- ly describe the control of the dynamic shutdown of the simulator.
