Dynamic simulation of chemical process as a tool to teach "the real problem" of identification and control

Simulation is the construction and use of a computer based representation, or model, of some part of the real world as a substitute vehicle for experiment and behavior prediction. In an environment of change, as the control of a chemical process, it offers an attractive opportunity for future engineers to try out the real control problem. The paper examines the practical use of simulation, within process control application areas, and the benefits released by the undergraduate pupils. The discussion draws on a study of the employment of simulation, which serves as an authentic pilot plant, to design an adequate feedback SISO control structure of a distillation column. Concluding the paper, several proofs are carried out in order to identify the nonlinear system and then the controlled plant is tested for reference and load changes.
