Previous issue date: 2009-08-28 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The traditional processes for treatment of hazardous waste are questionable for it generates other wastes that adversely affect people s health. As an attempt to minimize these problems, it was developed a system for treatment of hazardous waste by thermal plasma, a more appropriate technology since it produces high temperatures, preventing the formation of toxic pollutants to human beings. The present work brings out a solution of automation for this plant. The system has local and remote monitoring resources to ensure the operators security as well as the process itself. A special attention was given to the control of the main reactor temperature of the plant as it is the place where the main processing occurs and because it presents a complex mathematical model. To this, it was employed cascaded controls based on Fuzzy logic. A process computer, with a particular man-machine interface (MMI), provides information and controls of the plant to the operator, including by Internet. A compact PLC module is in charge of the central element of management automation and plant control which receives information from sensors, and sends it to the MMI / Os processos tradicionais de tratamento de lixos perigosos s?o question?veis por gerar outros res?duos que afetam negativamente ? sa?de das pessoas. Como tentativa de minimiza??o desses problemas foi desenvolvido um sistema de tratamento de res?duos perigosos por plasma t?rmico, uma tecnologia adequada por produzir altas temperaturas, impedindo a forma??o de poluentes bastantes t?xicos ao homem. O trabalho aqui exposto traz uma solu??o de automa??o para essa planta. O sistema disp?e de recursos de monitoramento e prote??es locais e remotos, que garantem a seguran?a do processo e dos operadores. Para controle de temperatura do reator principal da planta foi dada uma aten??o especial por ser o recinto onde ocorre o principal processamento e por apresentar um complexo modelo matem?tico. Para esse fim, foram empregados controles em cascata baseados em l?gica Fuzzy. Um computador de processo, com uma interface homem-m?quina (IHM) espec?fica, disponibiliza ao operador informa??es e controles da planta, inclusive via Internet. O elemento central de gerenciamento da automa??o e controle da planta fica a cargo de um m?dulo CLP compacto, que recebe as informa??es dos sensores, e as envia ? IHM
