    Abstract

    In this work, the dynamic behaviors of a complex pneumatic reducer valve have been studied through the pseudobond graph modeling technique. This modeling approach graphically describes the energy and mass flows among pneumatic valve components during real operational conditions. State equations have been derived from the pseudobond graph model and have been numerically solved by MATLAB-SIMULINK. To validate the accuracy of the model, simulation results are compared with the real data of an experimental setup and good agreements between them are reported. The main advantage of the proposed model over other conventional approaches such as fluid dynamics theories is that it provides a physical model which accurately predicts the system's dynamic responses without any need to run huge computer programs or establish expensive experimental setups.
