N2 - The present work shows the design of a new control scheme of two degrees of freedom based on the Smith predictor structure. This new proposal is compared with the Filtered Predictive Proportional and Integral controller and with the two degrees of freedom scheme of W. Zhang using the Integral Square Error and Total Variations of Control Efforts performance indexes. The results show that the new proposal allows to improve the performance and robustness when the process has variable delay.
