Abstract
The article describes the design and implementation of the control system of the didactic thermal exchange plant - pit000, located in the center of electricity and industrial automation, ceai - sena, as an investigative contribution to the needs of the institutions of education and of companies, sugar mills , petrochemical and paper mills, among others. The control system is based on a cascade strategy temperature-flow, implemented through the use of instrumentation and industrial control technology, which includes intelligent flow and temperature transmitters, programmable logic controllers and control valves with smart positioner. The design method of the control system included the development of diagrams (p & id) and strategy blocks, the definition of conditions of operation of the process, the modeling of control loops by means of transfer functions, the design of the flow and temperature controllers, the determination of the tuning parameters making use of of matlab and the final implementation of the control system. The results of the research, which are associated with the implementation of the control system, are considered satisfactory, because they are validated with the simulation and test of the control strategy in the presence of operation, as well as the control strategy complied with the purpose of improving the behavior of temperature output of the product in the process.
