摘要
首先建立了大气紊流下的飞机本体短周期运动方程、驾驶员模型、Dyr den大气紊流模型及人机闭环系统模型 ;然后利用Matlab软件在时域内进行了数值仿真 ,仿真结果表明 ,对于装有电传操纵系统的飞机来说 ,大气紊流对驾驶员诱发振荡的影响不明显。
Firstly,equations of motions of aircraft short period in consideration of atmospheric turbulence,pilot model,Dyrden atmospheric trubulence model and the mathematics model of Pilot-aircraft closed-loopsystem are founded.Then this paper gives the simulation result in time domain and analyzes and effect of atmospheric turbulence on PIO.which indicates atnospheric trubulence has little influence on PIO for the aircraft equipping FBWS.
