We consider some of the issues of implementing the prediction and control algorithms of the companion paper (Heath and Wellstead 1994). The algorithms are suitable for setting in self-tuning mode by combining them with recursive parameter estimation algorithms. The problems of set-point tracking and offset handling are also considered. It is shown that if the two-dimensional process can be modelled as incremental, then the solution is particularly staightforward. Throughout, the results are illustrated by simulations.
