Resumo: | A proposal to control the pH of the broth in sugar mills is presented in this work. Because it is a system with nonlinear characteristics and disturbances, the conventional control methods do not satisfy the usual requirements of the process. Among these conventional methods, we highlight the PID controller, which is basically linear. Extending the possibilities of action, the control proposal presented in this work proved to be quite satisfactory, by using fuzzy logic in a predictive way in the consideration of the effect of the disturbances in an intelligent way. The details of the proposed controller are presented, including some simulation results. The effectiveness of the proposed controller is illustrated by simulation, showing graphically the disturbances and the consequent control action, which eliminates the steady state error. The comparison of the results obtained with conventional PID controllers and the fuzzy controllers shows the predictive action of the fuzzy controllers allowing a significant reduction in the variability of the steady state error. In addition, this architecture can be modified to include other disturbances for other applications. Thus, the present proposal can be used in general to control non-linear and multivariable systems. |

Como se trata de un sistema con perturbaciones y características no lineales, los métodos de control convencionales no cumplen los requisitos habituales del proceso. Entre estos métodos convencionales, destacamos el controlador PID, que es básicamente lineal. Al ampliar las posibilidades de acción, la propuesta de control presentada en este trabajo demostró ser bastante satisfactoria, utilizando una lógica difusa de manera predictiva al considerar el efecto de las perturbaciones de una manera inteligente. Se presentan los detalles del controlador propuesto, incluidos algunos resultados de simulación. La efectividad del controlador propuesto se ilustra mediante una simulación, que muestra gráficamente las perturbaciones y la acción de control consiguiente, que elimina el error en el estado estacionario. La comparación de los resultados obtenidos con los controladores PID convencionales y con los controladores fuzzy muestra la acción predictiva de los controladores fuzzy, lo que permite una reducción significativa en la variabilidad del error en el estado estacionario. Además, esta arquitectura se puede modificar para incluir otras perturbaciones para otras aplicaciones. Por lo tanto, la presente propuesta se puede utilizar en general para controlar sistemas no lineales y multivariables.Uma proposta para controlar o pH do caldo em usinas de açúcar é apresentada neste trabalho.
