The present thesis work develops a control system based on neural networks applied to production of alcohols in an existent distiller in the laboratories of the Universidad Nacional de Ingenieria in Lima Peru. The distiller is constituted by four elements, the boiler or paila in which is carried out the separation of the alcohol for heating thanks to the different points of evaporation of the alcohols, a condenser whose function is the one of cooling the vapor taken place by the paila, a controller C – control II station manufactured by Conrad in charge of carrying out the control, sensors and actuadores characteristic of the process. The process is a multivariable, in which the variables that are wanted to control are the temperature and the degree of alcohol of the final product. To carry out the control of temperature it was designed and it implemented a neural networks of two in, two out and two layers of neurons, with eight neurons in their hidden layer. The temperature of the boiler was measured by termoresistance PT100 and a conditioner of signs Sitrans T of Siemens and controlled by heaters inside the paila, worked by contactors of Telemecanique, the methodology for the design of the control of temperature consisted on gathering data of the process implemented with a control on/off and to make that the neuronal network learns the answer from this to different entrances of the process and through generalization property to act in a correct way with not learned data. To control the degree of alcohol it was designed and it implemented two neural networks of one in and one out, two layers of neurons, with eight neurons in their hidden layers, these nets take charge of the process of sign adaptation coming fromtwo sensor Fígaro TGS 2260, and it is controlled by three bombs in charge of separating the final product according to the set point of the users. The system Scada it was implemented using Excel (Excel Scada) for the interaction of the system with the final user. The obtained results demonstrate that the neural networks carried out the prospective control with a stable answer of the process and the final product was of the prospective quality.
