关于一种人-机闭环品质评价方法的分析

Analysis on Evaluation Method of Handling Qualities of Pilot and Aircraft System

运用结构驾驶员模型研究人机闭环系统，根据Ｈｅｓ建立的衡量任务完成难易程度的模型和驾驶员的评价函数，拟定了飞行品质的计算方法．针对２个被控对象模型进行了飞行品质的计算．分析了驾驶员剩余、系统输入、大气紊流以及驾驶员模型参数变化对驾驶员评价品质的影响，以便更透彻理解和揭示Ｈｅｓ提出的操纵品质评价指标的内涵，这对飞机设计应用具有实际意义．

The closed loop system of pilot aircraft is studied,which is made up of the structural model of human pilot and the equivalent longitudinal model of aircraft. Based on evaluation function of the pilot work load proposed by Hess,the pilot opinion rating of the handling qualities is calculated for two controlled elements, the effects of the command signal, the atmospheric disturbance, the remnant of the human pilot ,the changing of the pilot model parameters on the pilot opinion rating of aircraft handling qualities are analysed to understand completely and expose the essence of the evaluation of the handling qualities proposed by Hess.
