Modelamiento y Simulación de un Sistema Electro-Neumático

Abstract

This paper develops a mathematical model for an electro-pneumatic system. The selected case of study is an electropneumatic pressure regulator valve, however the procedure is applicable to any system that respond to physical laws. The valve of this study is not physically available so this paper presents a theoretical analysis model based on similar articles and datasheets where the results shown through simulations are used before it validation. For this purpose we divide the valve in three subsystems where their equations were established separately and grouped to form the complete mathematical model. The model represents the behavior of the valve´s outlet pressure to an analog input voltage. After obtaining the model, it was translate to programming language in three different simulators showing the results of the variables of interest across the time in each programs.
