Experimental Friction Identification of a DC Motor

The paper deals with experimental friction identification method of a DC motor. For precise positioning tasks a friction phenomenon plays a large problem. For this a friction has to be identified and subsequently compensated if it is important. At first the paper deals with basic friction models. In the next section the DC motor mathematical model is stated. The DC motor friction identification is based on basic Newton′s motion equation of motor. The friction course by means of Matlab and measuring card is measured. For experimental results verification the simulation of mathematical model is used in comparison with real motor. The results are in the graph shown.
