摘　　要：研究飞行器鲁棒性准确测量问题。飞行器鲁棒性测量过程中受气动特性、大气环境变化剧烈导致动压快速变化,气动弹性和气动加热联合导致飞行器鲁棒性数据非真实变化。传统的测量方法处理这种变化时,无法准确获得真实数据,常借助大量经验数据作为检验数据,导致对飞行器的鲁棒性做出一个大致判断测量结果不准确。提出一种AADL模型的飞行器鲁棒性定量评价方法,通过建立飞行器鲁棒性AADL模型,添加新的飞行器数据类型扩展AADL模型测量能力,设置模型内各属性的取值范围,描述飞行器数据属性,为AADL模型设计一种调节算法,可以较为直观地对不同飞行控制系统鲁棒性能的优劣做出比较,从而解决了飞行控制系统鲁棒性复杂评估困难的问题。仿真结果进一步验证了该算法的有效性。The accurate measurement of air vehicle robustness was researched in this paper. We presented a quantitative evaluation method for air vehicle robustness measurement based on AADL model. Through the establish ment of AADL model for air vehicle robustness and the new added data types of air vehicle, the measurement capabil ity of AADL model was extended. Then the range of each attribute within the model was set and the data attributes of air vehicle were described. It provides a regulation algorithm for the AADL model that can be made more intuitive compared with pros and cons for the robustness of different vehicle control systems, so as to solve the difficult prob lem of complex flight control system robustness assessment. Tile simulation results further validate the effectiveness of the algorithm.
