I tried to estimate angular acceleration of a shaft with angular velocity points collected from an incremental encoder but, when I differenciate numerically, errors of estimation became very high due to the delay in capturing flanks (detecting slits). What alternatives do you suggest for my velocity and acceleration measurements? The real velocity follows a rectified sinusoidal waveform with 150 rpm as maximum amplitude and 0 rpm as the minimum amplitud. The minimum and maximum values for the period of the rectified sine wave are 0.5 seconds and 2 seconds respectivelly.
