摘　　要：对人-机闭环系统进行数学建模,基于Neal-Smith频域准则,对建立的模型进行参数匹配。在该模型条件下,以对驾驶员诱发振荡(Pilot Induced Oscillation,PIO)现象的产生机理及诱发因素的研究为基础,深入探讨了在恶劣环境下PIO的防范方法,并利用Neal-Smith频域准则对该防范方法进行评估。通过开环特性和闭环特性分析,确立了引入杆位移抑制滤波器的方法来有效抑制PIO的发生,为飞机设计研制过程中有效防范PIO提供借鉴和参考。A mathematical model of the"man-machine"closed-loop system is constructed,based on the Neal-Smith fre⁃quency domain criterion,parameter matching of the constructed mathematical modeling of the"man-machine"closed-loop system is performed.On the basis of the research on mechanism of inducing factors of the PIO phenomenon,the prevention method of PIO in the bad environment is explored under this model,and the prevention method is evaluated by using the Neal-Smith frequency domain criterion.Through the analysis of the open-loop and closed-loop characteristics,a method of introducing the bar displacement suppression filter is established to suppress the occurrence of PIO.The results show that the PIO can be effectively suppressed by introducing the bar displacement suppression filter,which provides a reference for the future aircraft design and development process to effectively prevent PIO.
