摘　　要：针对现代战斗机大多采用多控制面结构,导致飞控系统变得越来越复杂,传统的可靠性分析方法变得很难实现的现状,提出了运用蒙特卡罗法研究飞控系统可靠性仿真技术,为评估飞控系统可靠性提供了一种新方法,方法不仅可得到传统的性能指标而且能得到动态的仿真结果,为设计飞控系统提供了动态参数。给出了蒙特卡罗仿真步骤和算法,在仿真中考虑到了多种影响因素,更真切地模拟飞控系统的工作环境,结合实验数据进行仿真,验证了蒙特卡罗仿真在飞控系统可靠性评估中的可用性。In view of the fact that most modern fighter planes adopt multi - effector configuration, thus resulting in more complicated flight control system, so the traditional reliability analyzing methods become difficult to meet the requirement. By using Monte Carlo - method for the flight control system reliability simulation, a new method for the flight control system reliability evaluation is proposed, which can get not only traditional performance but also the dynamical simulation results, and offers dynamic data for designing flight control system. The algorithm and simulation steps are given, a variety of factors in the simulation are considered to simulate actual working environment for flight control system. Through simulating with experimental data, the Monte - Carlo simulation availability is verified in the assessment of the flight control system reliability.
