Smith-predictor-based Control

  • Chapter
Control of Integral Processes with Dead Time

Part of the book series: Advances in Industrial Control ((AIC))

Abstract

When the dead time of the integral process is significant, traditional control schemes such as those seen in the previous chapters might not be sufficient to obtain the required performance. In these cases, a dead time compensator can be considered. The most well-known control scheme where a dead time compensator is implemented is the Smith predictor, which, however, in its classical implementation, fails to provide a null steady-state error in the presence of a constant load disturbance if the process exhibits an integral dynamics. For this reason, mainly, different modifications of the classical Smith predictor have been proposed in the literature to overcome this drawback. These approaches will be reviewed and compared in this chapter.
