摘要: 本文介绍实用的驾驶员数学模型,分别研究了人-机械操纵系统(含杆系动态特性、非线性因素)-飞机以及人-控制增稳操纵系统-飞机组合系统的驾驶员诱发振荡问题,驾驶员模型中参数变化茄机械操纵系统中非线性因素对驾驶员诱发振荡的影响。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。

Abstract: This paper presents a practical mathematic model of pilot.The PIO (pilot-induced oscillation)problem of synthetical system of "men-mechanical contrtol system (containing the dynamic characteristics of the mechanical stick system and the nonlinear effect)-aircraft" and "men-control augumentation sy tem-aircrraft" is discussed.The influence upon PIO of the parameter variations in the pilot model and the nonlinear effects of the mechanical control system is analysed. Some good results have been obtained.These results are also useful in the study of the PIO problem of "men-Fly by control system-aircraft" synthetic system.
