摘要
设计了一种自适应差分滤波器滤除减摇鳍加载系统中的噪声,利用一阶差分对原始数据的噪声点进行识别与纠正,自适应地调整差分滤波器的检测阈,在严重冲击干扰时,经自适应差分处理之后,再采用算术均值滤波法进行平滑处理,实际应用的结果表明该算法可有效地抑制减摇鳍加载系统的噪声干扰。
In this paper,an adaptive differential filter for noise removal in fine stabilizer loading system is proposed.The recognition and correction method for noise point by using first order differential is introduced.So the detecting g-ate of differential filter is adjusted adaptively.It is stated that under heavy shock disturbance after processing with the adaptive differential filter,the influence of random interference can be eliminated by average method for sm-oothing.The actual results demonstrate that the filter has better performance in the removal of noise from highly corrupted signals.
