A systematic procedure to obtain the block diagram model from the bond graph model

摘要

The bond-graph method for the analysis of systems dynamics is very widespread in engineering and, because of its simplicity and its advantages, it has been developed a lot in the last decades. The bond graph model is a diagram which describes the manner of transmitting and transforming the power in a system, starting from the source up to the final elements. One of the most preferred ways of using the bond-graph diagram is the construction of the block diagram, appropriate for an adequate soft, the most frequently used one being MATLAB-SIMULINK. The block diagram model has a wide range of application in the study of systems dynamics because of its great advantages in case of numerical simulations. The manner of obtaining the block diagram from the bond-graph diagram is left at researcher choice, because there are no clear and well-defined procedures. The work presents a systematic procedure which contains several well-defined steps that lead to an exact and unitary approach of this problem.
