Fuzzy Smith Predictor vs Smith Predictor: An experimental evaluation for a thermal process with dead time

This paper reviews two practical implementations of a Smith Predictor scheme applied to a thermal process using a TCLab device. The findings are presented on a qualitative comparison with ISE and ISU quantitative performance values, as well as the settling time measurement. An acceptable response was obtained with the controllers of both proposed models. However, the Fuzzy Smith Predictor has a significant advantage over the Smith Predictor in terms of the time required for the response curve to reach and stay within a range of 5% of the reference value.
