Zusammenfassung

In this paper we present the time delay compensation through the design of control strategies like Filtered Smith Predictor, Modified Smith Predictor (MSP) and Predictive Control, for stable, unstable and non-minimal phase multivariable processes. Three case studies are used, where the behavior of each strategy is shown by simulation, according to the dynamic characteristics of the process. The simulation results are obtained by Matlab® and the comparison of the control strategies used is performed by the time performance of the controlled system, rejection of disturbances, monitoring of references and handling of uncertainties. In addition, a modification to the MSP is presented for the case of disturbance in the load. The simulation results show that the performance of the proposal is higher than the original MSP version.
