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。
Aviation fire control system, by its very nature, is a closed-loop man-machine system, “people (ie pilots)” is an important part of the system. Therefore, in the simulation, to find out a real pilot model is a key step to complete the simulation task. This paper introduces the multi-axis pilot model currently widely used in terminal aviation weapon launch simulation (TAWDS) Work principle, and try to draw the root locus diagram of its closed-loop characteristic equation by the root locus method to determine the selection range of the model parameters. Finally, taking the F-106 as an example, the e-Lv and e-Lw time-domain response curves are analyzed preliminarily, which shows that the simulation results are in good agreement with the actual situation. Therefore, the pilot model is usable. In addition, this model can be used as a reference or reference in the research of other fire control systems.
