| 摘 要： | 飞机的飞行品质不仅取决于飞机本体动力学特性和驾驶员操纵动力学特性，更重要的是取决于驾驶员─飞机系统闭环特性。通过一名驾驶员在模拟工作台上，完成对某机在不同飞行状态下的俯仰跟踪仿真任务，辨识得出驾驶员操纵动力学模型；对驾驶员─飞机闭环系统数学模型进行数字仿真得出系统动态响应；再按Ｎｅａｌ—Ｓｍｉｔｈ准则评价了该机的飞行品质，并且与按ＭＩＬ—Ｆ—８７８５Ｃ规范要求的飞行品质进行了对比。

| Abstract: | The flying qualities of aircraft depend not only on the dynamic characterof the isolated aircraft and control behavior of pilot, but also on the dynamic character ofthe closed loop system of pilot and aircraft. In this paper, the pilot model is identifiedfrom the simulation experiment of the pilot-aircraft, in which the pilot carries out acompensatory tracking task on the fixed simulator for several flight states. Then a pilot-aircraft model system is developed to calculate the system response and to evaluatethe flying qualities based on the Neal-Smith criterion. At the end of the paper, the flying qualities are compared and analyzed, which are evaluated based on the Neal-Smithcriterion and the criteria in MIL-F-8785C. |
