že selection of the suitable model is a compromise between the obtained modeling accuracy and calculation complexity. In the model with distributed parameters, it is assumed that the inertias of the motor, sha³, and load machine are split through the axis of movement. žis model can ensure the best accuracy of results; it is characterized by an inŸnite degree of freedom. However, the equations describing the system are the partial di¦erential equations with the form inconvenient for control structure analysis. žerefore, in the analysis of the system with ¹exible joints, the di¦erent models, which reduce the threedimensional phenomena, are utilized commonly.
