Digital Control of the Halden Boiling Water Reactor by a Concept Based on Modern Control Theory

The development of a concept for the control of a boiling water reactor by an on-line digital computer is described. The concept is based on the principles of Modern Control Theory. Experimental results are presented which compare digital control and analog control for equivalent perturbations. It appears that the digital control, which uses more process information than the analog control, handles perturbations more effectively.
