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．
Analysis of subsystem (component) performance index overshoot on the overall performance of flight control system is an important project proposed by the actual project. Based on the idea of hierarchical and hierarchical analysis, the sensitivity analysis technique and the simulation experiment are combined to study the influence of the uncertainty of the subsystem performance parameters on the stability of the flight control system, and some valuable analysis results are obtained.
