Paper Abstract

This paper presents a straightforward way to decode a quadrature shaft encoder output in order to obtain an accurate estimate of velocity linear actuators. The resolution of the implemented velocity sensor will be theoretically estimated and experimentally measured. A digital signal processing method to overcome the inherent error of the method at low speed will be discussed. Optical encoder combines high accuracy with low cost and is, therefore, in widest use for position feedback. Optical encoders are also used in linear configuration for machine tools.
