m ABSTRACT Masters Thesis INVESTIGATION OF THE SITUATION OF THE FEEDING THE SAME LOAD WITH TWO DIRECT-CURRENT MOTORS, BY BOND GRAPH METHOD Abdulnasir YILDIZ Fırat University Graduate School of Natural and Applied Sciences Depertment of Electriciai and Electronics Engineering 2002, Page: 55 In this thesis, the case of the two direct-current motors feeding the same load was investigated by using the bond graph method. The series and parallel case of the two motors were investigated separately. For this aim, firstly, the bond graph method was introduced. Then, the bond graph models of the both systems were obtained. After then, the change of armature currents and angular velocities of the systems with respect to time was obtained graphically from the program of Enport simulation. Finally, to illustrate the accuracy of the results obtained from the Enport simulation of the systems by using the bond graph method, the Matlab simulations of the same systems were implemented, and results were compared. KEY WORDS: Bond Graph, Enport, Matlab.
