Diseño e implementación de un sistema virtual para un sistema multivariable no lineal de cuatro tanques

Abstract

This work presents a virtual system which allows students to interact and perform laboratory practices in the area of industrial process control, obtaining knowledge regarding multivariable systems in a dynamic way. Therefore, he conducted the study of the non-linear multivariable four-tank system, analyzing and developing the interaction of system variables, coupling, decouplers and four control schemes among which are Integral Derivative Proportional (PID), Internal Model Control (IMC), Controller Synthesis (SC) and Sliding Mode Control (SMC). A mixing tank system (variable delay) and chemical reactor (reverse response) was added. The design was made using Labview software considering the need for a virtual system that provides the necessary tools that allow the user to start from understanding the operation of the multivariable open loop system until obtaining results after implementing the designed controllers. For this, several interactive windows are presented. Four laboratory practices were developed with the purpose of corroborating the operation of the virtual system through experimental tests at simulation level.
