Diseño de un sistema de control avanzado para regular la velocidad de una turbina de vapor acoplada a un generador DC
espanolEl articulo presenta la metodologia para el diseno de dos estrategias de control, LQG (Linear Quadratic Gaussian Control) y DMPC (Discrete Time Model Predictive Control), para regular la velocidad de una turbina de vapor acoplada a un generador DC de excitacion independiente. La dinamica del sistema es representada por un modelo lineal en el cual los parametros del modelo se calculan a partir de un algoritmo de optimizacion. Las estrategias de control se implementan en el sistema de control distribuido (DCS), Delta V. El objetivo es mantener constante la velocidad ante variaciones de la presion en la tuberia de vapor y modificacion de la resistencia del bobinado de campo del generador DC. EnglishThe paper presents the methodology for the design of two control strategies, LQG (Linear-Quadratic-Gaussian Control) and DMPC (Discrete Time Model Predictive Control), for speed control in a steam turbine coupled to separately excited DC generator. The dynamics of the system is represented by a linear model in which the model parameters are calculated using an optimization algorithm. The control strategies were implemented on a distributed control system (DCS), Delta V. The goal is to maintain the speed constant despite the variation of pressure in the steam pipeline and changes in the field resistance of the DC generator.
