| 摘 要： | 用同一理论来预测评价飞机飞行品质和驾驶员诱发振荡(PIO)是最近提出的一种方法.它是基于改良的补偿驾驶员结构模型和提出一套确定其模型参数的方法,并用驾驶员感受反馈信号的功率谱来衡量飞行品质和PIO.同一理论既适用人-机线性系统,也适用非线性系统.针对某电传操纵飞机,用同一理论进行分析,其结果与其它准则作了对比,最后并分析了速率限制环节、延迟环节等的影响.

| Abstract: | A unified theory is offered that can provide predictions of handling qualities levels and PIO(pilot induced oscillation) rating levels in single-axis tracking tasks, with linear or nonlinear vehicle dynamics. The theory is derived from the feedback topology of the structural model and a set of rules for selecting this mode's parameters. It is then applied to a hypothetical aircraft with and without rate limiter to analyze handling qualities and PIO. These results match well with other criteria. In addition, some parts of model are also discussed to provide for selecting parameters. |
