Graham C. Goodwin has made a lasting impact on both the theory and real-world industrial applications of control systems science. Dr. Goodwin and his colleagues were one of the first to produce a rigorous proof of convergence of discrete-time deterministic and stochastic adaptive control algorithms. The paper detailing this breakthrough was named one of the 25 most influential papers of the 20th century on control. In the area of digital control, Dr. Goodwin was the first to recognize that the “Z-Transform” was inappropriate for high-speed sampling, and developed what was named the “delta operator.” He demonstrated that there were significant numerical advantages to working with increments rather than absolute measurements. This line of research has many ramifications in practical aspects of signal processing and control.

An IEEE Fellow, Dr. Goodwin is currently a Laureate Professor and Director of the Australian Research Council Centre of Excellence for Complex Dynamic Systems and Control at the University of Newcastle, Australia.
