Abstract

A digital method to measure angular velocity for machine control applications is described. The method uses a phase-locked loop to multiply the frequency and reject the jitter. The process for measurement is completed in a very short time, providing not only quick readouts, but also information on transient velocity. Since the sampling intervals are fixed, measurement of angular acceleration can be obtained almost immediately
