Abstract
While he was trapped in a Shell oil refinery for weeks during a 1973 plant strike, Charles R. Cutler (1936-2020) used the opportunity to try out his untested theories on a new method for controlling chemical plants on the actual refinery. They worked spectacularly, and the resulting Dynamic Matrix Control method later became a standard part of control engineering practice. However, DMC was kept a trade secret at Shell until 1980 when it was first made available to the public. This book uncovers the history behind the theory by publishing Cutler’s writings and letters, including his 1969 thesis proposal letter to Prof. Huang at the University of Houston outlining his theories, and a more developed draft paper from 1975 that was never published. Science historians and control engineers alike can trace the development of the theory over time from its earliest origins.
