RESUMO:

This work considers the difficulties involved in the control of higher order systems with transport delay, where the solution adopted to mitigate the effect caused by the delay is the use of a prediction algorithm composed of the Smith Predictor techniques and Filtered Smith Predictor. Analyzing the cases where the system model used in the prediction algorithm is not perfectly identical to the real system, the presence of error in the system dynamics was observed. This error may amplify the control effort and cause premature wear of the equipment involved, in some cases leading to system instability. In this manner, the development of a tool to treat uncertainties originated from the difference between the system model and the real system, thereby reducing the effect of transmission delay of the control system, has been proposed. A software to adjust the process model and thus improve the dead time compensation was implemented.
