| 摘 要： | 驾驶员在环振荡判定准则较多,其中Neal-Smith准则的应用较为普遍.但Neal-Smith准则并不能准确反映PIO趋势,与驾驶员评估结论也存在一定差异.根据Neal-Smith准则进行飞机纵向驾驶员在环振荡分析的基本方法与程序,结合系统频域响应估算工具,分析得出满足系统性能要求的驾驶员相位补偿和增益区域,并基于该区域面积定义了新的PIO判断准则.与现有Neal-Smith准则相比,新的PIO判断准则可反映一类和二类PIO趋势随闭环系统参数的连续变化情况.

Analysis of Neal-Smith criterion improvement |
| |
| Abstract: | There are many pilot-in-the-loop oscillation criteria,and the Neal-Smith criterion is popular.But Neal-Smith criterion can't reflect PIO tendency exactly and the results from Neal-Smith criterion have some differences from PIOR.With the basic approach and procedure of Neal-Smith longitudinal PIO analysis,combined with frequency response estimation tools,a pilot phase compensation and gain region which meet system performance requirements can be obtained.A new PIO criterion is defined based on the region.Compared with Neal-Smith criterion,the new defined PIO criterion can express the continuous change of PIO tendency with the parameters of pilot-in-the-loop system. |
