飞机操纵面故障的多参数预测模型

飞机突发性操纵面故障的准确预测对保障飞机安全可靠工作具有重要意义.对目前的飞机操纵面故障预测的主要方法均存在只考虑一个特征参数或单独考虑几个特征参数的不足,缺乏对各特征参数的统一考虑.基于操纵而故障往往表现为一种故障表征出多种特征信号,同一特征信号还可能反映了不同的故障的事实.借鉴灰色预测建模和信息融合的思想,提出了基于多故障特征参数的预测模型,使得多个相关特征参数时间序列不仅可以为各自的预测提供相关信息,也可为其他序列预测提供必要的信息,增加了预测的准确性;将模型应用于某飞机操纵面的故障预测中,经实例计算验证了模型的有效性.

Multi-Parameter Prediction Model of Flighter Control Surface Fault

Predicting the flighter control surface effectiveness loss and lock-in-place during air combat accurately has great significance to ensuring aircraft safety.At present,in the main flighter outburst configuration fault prediction methods,only one characteristic parameter is considered or several characteristic parameters are considered in isolation,there is a lack of consideration of the characteristic parameters together.Because flighter control surface fault often characterize as a variety of feature signa...
