Mr. Powers' interest in control theory began when he was a junior medical physicist at the Argonne Cancer Research Hospital in Chicago during the early 1950s. Since then he has carried on dual careers: an official one as a designer of electronic systems for science, medicine, and commerce, and an unofficial one as an explorer of the organization of living systems.

Now "retired" and living in Durango, Colorado, he devotes his full attention to the continuing research into Perceptual Control Theory (PCT) through the design of computer models of living control systems, in interaction with the Control Theory Group (a long-standing association of researchers in the field of control theory), and participating in scientific conferences and meetings. At the top of the list today is his forthcoming book, the third in the Living Control Systems series, with the working title: Living Control Systems III: Models and Simulations.

He has published numerous articles in scientific and technical journals as well as authoring four books currently in print. With Richard J. Robertson, Ph.D., Professor of Psychology, Northeastern Illinois University, Chicago, an “early adopter” of PCT, he co-edited the first introductory college text* on Perceptual Control Theory.
