.加速度积分位移 Matlab2013-02-04 05:30:00|分类:MATLAB应用|举报|字号订阅最近做有关加速度的数据处理,需要把加速度积分成位移,网上找了找相关资料,发现做这个并不多,把最近做的总结一下吧!积分操作主要有两种方法:时域积分和频域积分,积分中常见的问题就是会产生二次趋势。关于积分的方法,在国外一个论坛上有人提出了如下说法,供参考。Double integration of raw acceleration data is a pretty poor estimate for displacement. The reason is that at each integration, you arecompounding the noise in the data.If you are dead set on working in thetime-domain, the best results come from the following steps.1. Remove the mean from your
