These results are also useful in the study of the PIO problem of "men-Fly by control system-aircraft" synthetic system.
得出的结论对研究人-电传操纵系统-飞机组合系统的驾驶员诱发振荡问题也是有益的。
As an example, the lateral-directional PIO within the whole flight envelope boundary of JJ-7 aircraft are checked by use time domain methed, and tested by fixed-base simulator RJ-ⅱ.
文中以JJ-7飞机为例，采用时域法在整个飞行包线各点进行了检查，并用固基飞行模拟器进行模拟验证。
According to the essence of Pilot Induced Oscillation ( PIO) and the theory of Closed-loop control, the mathematical model of Pilot-Plane system is set up.
本文根据驾驶员诱发振荡的实质，从闭环控制理论出发，提出了人-机系统数学模型，并在时域内进行了计算。
Pilot Induced Oscillation ( PIO) is a series of problems brought by the instability of the closed-loop system of pilot-aircraft, and one of the most fatal factors which influence the flight safety.
驾驶员诱发振荡（PilotInducedOscillation，简称PIO）是由人-机闭环系统的不稳定引起的问题，是影响飞行安全的重要因素之一。
