This paper discusses a speed estimation problem of very low speed servo systems. Speed estimation can be easily done by conventional methods such as tachometer, observer, numerical differentiation and so on. However, speed estimation for very low speed systems still includes some engineering problems on precision. This paper proposes a simple way to derive a speed estimation by using the output difference in long duration and inputs sequence of the duration. We have also verified this method through an experiment of hydraulic servo system.
