MATLAB: Is there anyway to convert vibration acceleration data into velocity

Question

How can I convert the vibration acceleration data collected in real time to velocity ? I know the relation is to integrate the data but my system requires real time velocity monitoring. I appreciate your reply.

Thanks in advance

Answer 1

I already found the answer so I'll just post here if anyone need.

velocity = cumtrapz(acceleration-mean(acceleration));

-- The acceleration signal is subtracted from its mean() value in order to remove the DC components and prevent the unnecessary ramp in the velocity signal.

-- cumtrapz() Matlab function is used to integrate the acceleration data in real time using trapezoidal rule.
