MODELAMIENTO Y SIMULACIÓN DE UN SISTEMA DE LLENADO DE DOS TANQUES EN SERIE

Abstract

The main objective of our work is to model and simulate the performance of the filling of two tanks connected in series. For this, different inputs are used, specifically, step, pulse and ramp. We use different simulation programs such as: Matlab/Simulink, Scilab/Xcos and (Open) Modelica. Additionally, the performance of the simulation programs is evaluated. In order to simulate the system, first we find the mathematical model, which has been considered as the base model of a single tank system, facilitating the identification of the physical laws which govern the system. By using mathematical analysis, the differential equations of both models, one and two tanks, are obtained, note that the model is non-linear, and therefore has been linearized, managing to obtain the respective transfer functions for the simulation. Once simulated in each of the programs, a comparison is made between the positioning simulator Matlab and free license programs such as Scilab and Modelica, by obtaining boundary values at different simulation times, results show that Matlab can be replaced by Modelica, since reports the best performance in terms of computation time.
