Error compensation methods in speed identification using incremental encoder

Error compensation methods in speed identification using incremental encoder

This paper presents a comparative analyze between several methods that compensate or reduce the errors that occurs in speed identification using incremental encoder. The errors are caused by the lack of synchronization between encoder pulses and sampling time in fixed-time measurement and fixed-posi...

Beschreibung
Zusammenfassung:This paper presents a comparative analyze between several methods that compensate or reduce the errors that occurs in speed identification using incremental encoder. The errors are caused by the lack of synchronization between encoder pulses and sampling time in fixed-time measurement and fixed-position measurement, and also due to the delay between the reference speed and the calculated speed from the incremental encoder pulses. Simulation results, using Matlab/Simulink ® structures are presented and discussed.
