先进战斗机控制系统鲁棒性评估

摘要

发展了一种基于Monte Carlo方法的评价控制系统鲁棒性能的方法;提出了鲁棒度的定义,给出了具体的系统鲁棒性量化指标及计算方法;它能直观并且定量地得到系统在任意给定性能水平下的鲁棒度数值,从而可对不同控制系统鲁棒性能的优劣做出比较,得到更为全面真实的系统鲁棒性能的评价结果;并通过仿真验证了所提出的控制系统鲁棒性评估算法的有效性.%This paper investigates a method of evaluating robustness of control systems based on the Monte Carlo approach. The concept " robust degree" has been proposed to give specific quantity indicators of robustness and computing method. For any given performance requirements, this evaluation algorithm can intuitively obtain the robust degree to effectively select the optimal robustness, which is approved by the simulation.
