子系统性能参数变化对飞控系统稳定性的影响

INFLUENCE OF SUB SYSTEM PERFORMANCE PARAMETER UNCERTAINTY ON STABILITY OF WHOLE FLIGHT CONTROL SYSTEM

分析子系统（元部件）性能指标超差对飞控系统总体性能的影响，是实际工程提出的一项重要研究课题．本文基于分层递阶的分析思想，采用灵敏度分析技术和仿真实验相结合的手段，研究了子系统性能参数的不确定性对飞控系统稳定性的影响，得到了一些有价值的分析结果．

Analyzing the influence of sub system performance index beyond the bounds on the whole flight control system is an important task podes by practice engineering.This paper presents a hierarchical analysis method,using singular value sensitivity technique of sub system performance parameter uncertainty on the flight control system stability.Some valuble results are derived.
