| 摘 要： | 采用系统灵敏度理论，以修正的带宽准则，增益和相位裕度准则以及Ｎｅａｌ－ｓｍｉｔｈ准则等飞机纵向驾驶员诱发振荡（ＰＩＯ）预测准则作为系统指标，建立了参数变化对诱发振荡预测指标影响的灵敏度公式，以ＪＪ７飞机为例，给出了飞机，操纵系统及驾驶员参数上述指标影响的灵敏度，根据计算结果进行了ＰＩＯ参数敏度预测分析，同时与数值仿真结果进行了对比分析。

| Abstract: | In order to establish the sensitivity formula which predict the influence degree of induced oscillation calculation, the system sensitivity theory is adopted, and system indices such as adaptation of bandwitch criterion , G m and P m criterion and Neal Smith criterion is taken in this article. The sensitivity of one flying state of JJ7 aircraft which are effected by aircraft, control system and pilot parameters also given in this article. Bases on it, parameter sensitivity of the pilot induced oscillation(PIO) are analysed and predicted. Finally, by contrasting this results with digital simulation results, some perorations are given. |
