چکیده
Electrical drives use frequently incremental encoders as position sensor. The paper deals with modeling and simulation of an incremental encoder and MatlabSimulink simulation structure is realized and tested. In order to process the information provided by the encoder it was built a structure to determine the direction of the rotation in an angular interval equal to a quarter of the angular step of encoder graduation. The encoder signal based position computation was also simulated. Experimental measurement were performed.
