针对飞机过度滞后会导致飞行员诱发振荡的问题，提出综合运用频域法和时域法对过度滞后与飞行员诱发振荡间的关系进行定量研究。建立了简化的人机闭环系统模型，分析了人机闭环系统不稳定的充要条件。频域内应用伯德图和尼柯尔斯图对有效飞机频域特性进行了分析，通过带宽准则和平均相位速率准则对有效时延与飞行员诱发振荡间的关系进行定量评估。时域内运用飞机的飞行员诱发振荡时间历程曲线及延迟时间与飞行品质评分间关系曲线，对过度滞后的影响进行了定量研究。研究结果可为控制飞机的过度滞后提供定量依据。

Excessive lags of aircraft could cause Pilot Induced Oscillations(PIO).The frequency domain method and time domain method were used combinedly for studying the relationship between excessive lags and PIO quantitatively.A simplified closed-loop aircraft-pilot system model was built up,and the aircraft-pilot system stability was analyzed.In frequency domain,the frequency characteristic of effective aircraft was investigated by using Bode plot and Nichols plot,and quantitative estimation was made to the relation of the effective time delay and PIO by using bandwidth criterion and phase rate criterion.In time domain,the influence of excessive lags was quantitatively studied by using pilot induced oscillations time history and pilot rating.The results can provide a quantitative reference for controlling excessive lags of aircraft.
