| 摘 要： | PIO是飞行仿真软件分析的最重要的内容之一。飞行员诱发振荡（PIO）是一种人-机闭环系统的不稳定的动态运动,通常由飞行员试图执行精确的飞行操纵任务所致。目前,已经研发出了大量的PIO理论用于预测PIO的敏感性,本研究仅对3个PIO准则进行理论研究和预测命中率分析,即带宽/俯仰速率超调准则、Smith-Geddes准则和Gibson相位速率准则。

Prediction for PIO for Flight Simulation Software |
| |
| Abstract: | PIO analysis is one of the most important parts in the flight simulation software.Pilot-induced oscillations（PIO） can occur when the pilot attempts to perform a precise control task and can,therefore,be treated as closed loop dynamic instability of the pilot-aircraft system.Currently,there exist numerous design criteria for the prediction of PIO susceptibility.However,in the paper only three criteria,including Bandwidth/Pitch Rate Overshoot,Smith-Geddes and Gibson Phase rate criteria,are reviewed and correlated to flight research data. |
