Abstract: In this paper a new approach to perform angular velocity
measurement of a motor is presented. The approach is
based on the use of PLL (Phase-Locked Loop) and is able
to perform high resolution measurements despite the use of
a low resolution encoder. A complete measurement system
was developed fusing the proposed approach and the classic
T method, allowing even the measurement of zero velocity
and the determination of the shaft rotation direction. In order
to validate the proposed approach, some parameters were
considered to compare its performance with the performance
of a classical method. To validate the proposed approach and
to compare it with the classical methods, some comparison
parameters were considered. The results obtained using
each method are presented and discussed, as well as the
comparison between them.2010-12-01T00:00:00Z
