摘要
研究了Gap准则,建立了速率限制舵机的描述函数模型、改进的Neal-Smith模型,介绍了描述函数法研究I类驾驶员诱发振荡(PIO)的机理,得到了Gap准则在预测纵向I类PIO中的计算方法。并应用Gap准则对飞机纵向I类PIO进行了预测,结果表明Gap准则能够有效的预测纵向I类PIO。
In this paper the gap criterion was researched, the description function of rate-limiting actuator was built up, and the Neal-Smith pilot model was perfected. The method of using description function for predicting Ⅱ PIO was presented. And the whole process to predict the longitudinal Ⅱ PIO was given. The result showed it was effective.
