Diseño de una estrategia de control y comparativa para Sistemas Multivariables Lineales Acoplados, descomponibles en sistemas Mimo Difuso VS PID.

Abstract

The present work deals with the development and verification of a methodology that allows the end user to tune a fuzzy controller for multivariable MIMO (Multiple Input Multiple Output) systems. This carries with it the search for articles that allowed to determine said methodology, addressing the relevant aspects. The strategy was carried out by simulating the POMTM model of a Wood-Berry methane-water distillation column. Through a series of steps described in this document where it is carried out from the identification of each of the functions contained in a multivariable system, the calculation of the decoupling mesh that allows eliminating the effect of one variable on the other, the tuning of the classic controller which will be used for the development of a fuzzy controller from the error, delta error and controller output signals to later carry out a confrontation between the controllers designed through a robustness analysis, a performance analysis through the ISE (Integral Squared Error), IAE (Integral Absolute Value Error), ISU (Integral Quadratic Control Output) and TVU (Integral Total Control Variation) indices. Corroborating the great performance of the fuzzy controller with respect to variable 1 and its two variable outputs with respect to noise.
