中文摘要：
等效系统拟配对于采用主动控制电传操纵系统的飞机的飞行品质评价具有重要意义。为了评价特定状态下飞机纵向整体品质的好坏，建立了综合考虑电传操作系统环节、驾驶员环节和大气扰动环节的人-机-环闭环系统。使用遗传算法对此高阶系统进行了降阶等效拟配，使用等效系统准则依据拟配后的等效参数进行了人-机-环系统的品质评价，并在驾驶员高延迟时间的条件下比较分析了使用等效系统准则与使用Neal—Smith准则得出的飞行品质的一致性。仿真结果说明了人-机-环闭环系统等效拟配评价的可行性、合理性。
英文摘要：
Equivalent system match is important in the flying qualities estimating process for the plane with active fly-by-wire control system.In order to assess the comprehensive longitudinal flying qualities in a certain state, the closed-loop pilot-aircraft-environment system that combined fly-by- wire control system pilot and atmospheric factors is established.The system is then matched to a low- order system by using genetic algorithm, the equivalent system criterion is taken to evaluate flying qualities using identified parameters.The similarity of qualities between the equivalent system criterion and the Neal-Smith criterion is analyzed in pilot＇s high delay situation. Simulation results show the idea for identifying high-order pilot-aircraft-environment system is feasible and rational.
