Title:Supervisory Control of Discrete-Event Systems: A Brief History
Abstract: This talk presents a brief history on the “supervisory control theory (SCT) of discrete-event systems”, as it has evolved in the period 1980-2017. We trace back to the early 1980s to introduce the background, need, and motivation for SCT. The relation between SCT and linear control theory is highlighted, in particular their common root on control-theoretic concepts and synthesis. SCT was created by Ramadge and Wonham and pinned down to the literature in 1987; we introduce the essence of this framework which is based on regular languages and their finite automata representations. Moreover, we summarize various extensions of SCT in the past three decades, with emphasis on a variety of control architectures that exploit horizontal and vertical modularity, as well as partially-observed control systems. Extensions to state-based models, timed systems, and applications to a wide spectrum of engineering practice are also presented.
