Abstract
This document will show the identification, supervision and control of a wastewater
treatment plant where the characteristics of the system or plant to be controlled
are multivariable and dependent on external factors such as inflow, concentration
of ammonium or the total suspended solids.
The work is proposed in different objectives to be solved, which include:
Identification of a plant through the graphical analysis of the response of
the system and the use of the PID Tuner application of Matlab for the
automatic identification of the plant and to compare the obtained results.
The description of the control technique used to design the PI controller and
its creation for each case of the multivariable system and, the use of the
Matlab autotuner application to determine the parameters of the PI
controller automatically to make a comparison of the results obtained in
each case.
Detection of PI controller inefficiencies using fixed gains for a multivariable
system through its response characteristics for a step input.
Research and design analysis of possible alternatives to classic PI control
such as Feed-Forward control or Fuzzy Logic Controllers (FLC).
The implementation of the possible control alternatives previously found in
the Simulink program to be able to simulate, analyze and compare their
responses with the previously designed PI controller.
The analytical comparison of the Fuzzy control with Feed-Forward control
and classic PI control using the characteristics of the simulated response
using Simulink for a step entry.
How to implement the two algorithms in a PLC through the models designed
and implemented with Simulink using the Matlab PLC Coder application.
The creation of the SCADA interface to monitor the process and simulate it
in an industrial environment to verify that the two algorithms converted to
block functions for the PLC work properly.
For the realization of the simulations and his comparison, have used tools like
Simulink of Matlab, and has implemented the control in an industrial environment
like the programming of PLC's and the SCADA's using the program of Rockwell,
RSlogix5000 and Wonderware InTouch for the creation of the SCADA interface.
At the same time, together with Javier Gàmiz, the creation of internships for the
Master’s has been created based on the work carried out. Se plantea el trabajo en diferentes objetivos a resolver, dentro de los cuales consta:
•Identificación de una planta a través del análisis gráfico de la respuesta del sistema y la utilización de la aplicación PID Tuner de Matlab para la identificación automática de la planta y comparar los resultados obtenidos.
•La descripción de la técnica de control empleada para el diseño del controlador PI y su creación para cada caso de nuestro sistema multivariable y la utilización de la aplicación autotuner de Matlab para determinar los parámetros del controlador PI automáticamente para hacer una comparativa de los resultados obtenidos en cada caso.
•La detección de ineficiencias del controlador PI utilizando unas ganancias fijas para un sistema multivariable a través de sus características de respuesta para una entrada escalón.
•Búsqueda y análisis de diseño de las posibles alternativas al control clásico del PI como pueden ser el control Feed-Forward o los controladores que utilizan lógica difusa llamados Fuzzy Logic Controllers (FLC).
•La implementación de las posibles alternativas de control encontradas anteriormente en el programa Simulink para poder simular, analizar y comparar sus respuestas con el controlador PI anteriormente diseñado.
•La comparación analítica del control Fuzzy con control Feed-Forward y control clásico PI mediante las características de la respuesta simulada utilizando Simulink para una entrada escalón.
•La forma de implementar los dos algoritmos en un PLC a través de los modelos diseñados e implementados con Simulink utilizando la aplicación PLC Coder de Matlab.
•La creación de la interfaz SCADA para monitorear el proceso y simular en un ambiente industrial para comprobar que los dos algoritmos convertidos a funciones de bloques para el PLC funcionan correctamente. The work is proposed in different objectives to be solved, which include:
