Diseño y simulación de esquemas PID lineales y no lineales con acción de reset aplicando lógica de control difuso a dos procesos químicos no lineales..

Abstract

This document presents a study of linear and non-linear control systems, especially Reset Control Systems and Fuzzy Control Systems, with special emphasis on their design and stability analysis. The present one carries out a study of the design and simulation of different control schemes, both linear and non-linear (NPID) with and without reset action; considering and not considering fuzzy logic. Two non-linear chemical processes are taken into consideration a mixing tank with variable delay and a CSTR reactor with Van Der Vusse reaction. To validate the results of each scheme, performance indexes (ISE, ITSE and TVu) and response characteristics in transitory state (overshoot ( ) and setting time ( )) are used. The results are presented in a graphical user interface (GUI), both processes are presented with their respective performance indexes and response characteristics in transitory state to setpoint changes and disturbances.
