Typical Application Possibilities for Self-Tuning Predictive Control

Abstract Control based on self-tuning prediction has some typical application possibilities. Two such realizations are described in this paper. The first one deals with dead-time control in a heat transport process. A predicted value of the process output is fed back, leading to a compensation of the time-delay. This allows for higher loop gains, resulting in a better control performance as is demonstrated by the comparison with a PI-regulator. The second implementation of self-tuning predictive control is in a decision-making strategy used in an electrical servo. This application shows that very satisfactory control performance can be obtained with rather primitive control tools (on-off) combined with a self-tuning predictor. The results of the strategy are compared to those of well-known control methods, among which a PD-controller.
