TL;DR: In this article, an expert system for closed single-loop control is described and an implementation based on YAPS and object-oriented programming is described. But this system can be compared with a real-time operating system.
Abstract: Different ues of expert systems in process control are discussed. The paper concentrates on expert systems for closed single loop control. Motivation for this is given and a prototype experiment is described. The experiment is evaluated and an expert control architecture is proposed. The system can be compared with a real-time operating system. An implementation based on YAPS and object-oriented programming is described.

TL;DR: In this article, two non- quadratic performance indices are proposed and myopic solutions computed for chip refiner, and the computation of the dual controller corresponding to these indices is discussed.
Abstract: On a chip refiner, the incremental gain between the motor load and the plate gap is subject to sudden changes due to pad collapse. Passive adaptive control with fault detection, active suboptimal dual control and dual control solutions are discussed. For the latter, the choice of the control criterion is crucial as it must reflect the peculiarities of the process. Two non- quadratic performance indices are proposed, and the myopic solutions computed. Simulations show the superior performance offered by those ladices. Future work will concentrate on the computation of the dual controller corresponding to these indices.
