某型飞行模拟器飞行性能验证数据预处理方法

摘要

针对飞行模拟器的性能验证问题,对验证之前所采集的试飞数据和仿真数据进行了研究,对仿真模型验证的数据预处理方法进行了归纳和总结并指出了局限性,提出了对于模拟器动态数据和静态数据进行数据选段、去除异常值、采样点匹配、平稳性检验和平稳化处理、零均值处理、各态历经性检验和正态性检验的一套处理方法,并利用这些方法对所获得的试飞数据以及仿真数据进行了处理,通过预处理的验证数据再用于具体飞行性能的检验.研究结果表明:该预处理方法能够将所获得的数据处理为符合下一步具体验证的数据,为下一步验证工作奠定基础.%Aiming at simulation performance verification problem of the flight simulator, the previously collected test flight data and simula-tion data was studied, the method of simulation model validation data preprocessing was carried on the induction and limitation was pointed out, A set of processing methods to dynamic data and static data of simulator was presented to passage data, remove outliers, sampling points matching, stationarity test and smooth processing, zero mean processing, ergodic property inspection and normality, and these methods were used to the flight test data and simulation data obtained for processing, the data after preprocessing was used for the verification of specific flight performance. The results indicate that the pretreatment method can be gained by the data processing to meet the specific data valida-tion, and the foundation of validation work is laid for the next step.
