基于飞机运动方程的逐步预测“野值”剔除方法

提出了一种基于飞机运动方程的逐步预测＂野值＂阈值确定和剔除方法,该方法根据状态的变化快慢,按6步根据有效简化的输出响应来逐步预测飞行状态和参数,每步按照设置好的阈值判定和剔除测量中＂野值＂。由于在实际测量中快变状态或参数存在＂野值＂可能性比慢变量大,而且输出响应具有工程上的精度,因此本方法对剔除飞行数据的＂野值＂更有效。

Abstract：

The threshold determination and outlier canceling methods by step-by-step prediction with flight motion equation was proposed.Based on the state change,this method can predict the flight state and parameter successive through simplified output response in six steps.In every step,the outlier is confirmed and cancelled under the preset threshold.During the actual measure,existential probability of outlier in the faster state or parameter is bigger than slow item,and its output response also has engineering precise,therefore this method is more effective for canceling the outlier in flight data.
