用于小幅值精确控制的纵向飞行品质准则

Longitudinal Flight Qualities for Small Amplitude Precision Control

研究用于评定飞机小幅值姿态和航迹精确控制的纵向飞行品质准则，提出以线性化小扰动飞机方程和飞控系统为评定对象，用等效系统拟配法、系统稳定裕度、ＮｅａｌＳｍｉｔｈ准则、姿态带宽准则、ＧＭ／ＰＭ准则和回落准则对整个飞机进行品质评价．综合分析这些准则的相互关系后，认为分别用上述６种方法评价飞机的飞行品质，可以得出该飞机的综合性能指标，而不至于得出一个片面的结论．

The longitudinal flight qualities for small amplitude attitude and t rack precision control are studied. It is proposed that lower order equivalent system, system stability, Neal Smith criterion, bandwidth criterion, GM/PM crite rion, dropback criterion are used to evaluate flight qualities, which is based o n linear airplane equation and flight control system. After analysing comprehen sively relation of these criteria, It is thought that if all of the six criteria are utili zed to evaluate flight qualities of aircraft, it will lead to the integrated con clusion which can reflect various performance of airplane, and not a unilateral result.
