This work presents the analysis and design of controllers for dead time compensation in the case of plants represented by parallel models and stable, integrating or unstable dynamics. The proposal is based on two control structures that are well established in the literature. The first is Smith’s filtered predictor, which is used to compensate for delay or dead time in a robust manner. The second is the cascade compensation, which by its characteristics allows to improve the rejection of disturbances. Simulation results are presented to show the advantages of the proposed controller compared to other recent ones in the literature.
