摘要
针对生产过程中的噪声影响,对车用锂电池薄膜的静态和动态测量厚度,采用移动平均,递归平均、中值滤波以及组合方式进行处理。通过期望和方差的比较表明:增加平均序列能提高滤波性能,移动平均结合递归平均属于最优算法。
For noise,film thickness of car lithium battery system is preprocess based on moving average,re-cursive average,median filter and the above combination method.The results from expectation and variance show that the increase in the average sequence can improve the filter performance,moving average with recursive average is optimal algorithm.
