Multistation supervisory control
Electrical Engineering, 1953THE USE OF supervisory control by power companies for the operation of remote stations has increased greatly during the past 10 years. Power-line carrier current is being used on large power systems to make possible the control of widely separated stations from a common point.

Supervisory control after perturbation
SMC 2000 Conference Proceedings. 2000 IEEE International Conference on Systems, Man and Cybernetics. 'Cybernetics Evolving to Systems, Humans, Organizations, and their Complex Interactions' (Cat. No.00CH37166), 2002Discrete event systems undergo perturbations, such as failures, that disrupt the control system and reduce the anticipation capacities of the future evolution of the process. Using the (max,+) algebra, processes modelled by a timed event graph may be represented by a linear model.

Supervisory control of timed automata
1999 European Control Conference (ECC), 1999Based on the framework of Ramadge and Wonham theory, this paper presents a methodology for the design of a supervisory control for timed discrete event systems. Timed automata in dense time domain are used as models. They are successively extended to region automata and r-region automata in which passing of time is considered as an event, either ...

Supervisory control is not a new development. It is, in fact, 17 years since the first equipment of such type was installed. To-day the system is becoming a necessary adjunct to the extensive distribution schemes in progress.

Experience with supervisory control
Electrical Engineering, 1932The Reading-Philadelphia suburban electrification has afforded a thorough trial of supervisory control equipment in actual operation. The experiences which have been secured with this equipment and which demonstrate its numerous advantages are described in this article.

Blocking and controllability of Petri nets in supervisory control
IEEE Transactions on Automatic Control, 1994Summary: This note discusses the use of Petri net languages in supervisory control theory. First it is shown that the trimming of an unbounded Petri net is not always possible and a new class of Petri net languages, that may be generated by nonblocking nets, is defined.

An A-C. Supervisory Control System
Transactions of the American Institute of Electrical Engineers, 1931A supervisory control system operating entirely on alternating current and possessing great reliability is described in this article. With a suitable switchboard arrangement, the operator is said to be able to visualize switching conditions at a glance; the system has the further advantage of employing only equipment with which operators are familiar.

Modular Supervisory Control and Hierarchical Supervisory Control of Fuzzy Discrete-Event Systems
IEEE Transactions on Automation Science and Engineering, 2012This paper establishes modular and hierarchical supervisory control theories of Fuzzy Discrete-Event Systems (FDES). It aims to resolve the horizontal and vertical complexities present in large-scale event-driven systems, which are affected by uncertainties in their event and state representations.

An algorithm for hierarchical supervisory control
Computers & Chemical Engineering, 1995Abstract A scheme for implementing hierarchical steady-state control objectives is presented in this paper. These objectives are implemented through a supervisory controller which provides setpoints to a standard regulatory control system. The setpoints are calculated through a sequence of optimization subproblems structured in such a way that ...
