一个飞行员模型

航空火控系统,就其实质而言,是一个闭环的人机系统,“人(即飞行员)”是该系统的重要组成部分。因此,在仿真中,找出一个真实可用的飞行员模型是完成仿真任务关键的一步,本文介绍了目前在终端航空武器投放仿真(TAWDS)中广为应用的多轴飞行员模型,分析了该模型的工作原理,并试图通过根轨迹法,绘制出其闭环特征方程的根轨迹图,以确定该模型参数的选取范围。最后通过以F-106飞机为例,对所得的e_(Lv),e_(Lw)时域响应曲线进行了初步的分析,说明其仿真结果和实际情况是基本吻合的,因而,该飞行员模型是可用的。另外,此模型在别的火控系统的研究中,也可作为借鉴或参考。

A Pilot Model

An airborne fire control system is a common closed loop controlledman machine system.Here man,i.e.,the pilot,is an important part of the sys-tem.Therefore the finding of an authentic practical model of the pilot is the keyprocess of the simulation,A multi-axis pilot model which is widely used in TAWDS(Terminal Aerial Weapon Delivery Simulation)is introdudce and it's operating prin- ciple is then analysed in this paper,The root locus diagram of characterisic equat-ion of the closed loop is obtained using the root locus method to determine the rangeof the parameters setting in the model.Finally the e_(LV),e_(LW) time response curveof F-106 plane is initially analysed.The result indicates that the practical situationtallies basically with the simulation.Therefore the ralated model of the pilot is pra-ctical.Besides,the model can also be referenced in the studies of other fire controlsystem.
