Evaluation of three optical-encoder-based speed estimation methods for motion control.

Evaluation of three optical-encoder-based speed estimation methods for motion control.

Three speed estimation methodologies: pulse count, elapsed time, and constant sample-time digital tachometer (CSDT) methods, used with optical incremental encoders, are implemented and compared in a closed-loop system setup using a specialised...
