Sammanfattning

The problem of controlling delayed systems has been widely studied in the control community. The Smith predictor (SP) scheme was
the most famous and efficient technique to cope with this problem. Afterwards, robustness problems and those related to the control of
integrating and unstable delayed processes were resolved. This work presents an interactive tool for studying and understanding the
different alternatives available for controlling systems with large delays. Interactive tools have provided excellent support for the control
community during recent years. In this sense, the tool developed here helps to compare easily the performance of PID controllers and SP
approaches for processes with delay, as well as other control structures used to solve different problems that the original SP has when
integrator and unstable models are employed. Robustness problems due to presence of model uncertainties can also be analyzed.
Furthermore, some real industrial processes are also described as motivation in the study of the problems presented in the paper. The
tool incorporates a set of typical transfer functions based on these real industrial processes.
