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 Algorithms
2013In all types of hybrid vehicles, a supervisory controller must determine how the powertrain components should operate, in order to satisfy the power demand of the drive line in the most convenient way. The main objective of that optimization is the reduction of the overall energy use, typically in the presence of various constraints due to driveability

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.

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.

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.

Decentralized supervisory control with communicating controllers
IEEE Transactions on Automatic Control, 2000The decentralized control problem for discrete-event systems addressed in this paper is that of several communicating supervisory controllers, each with different information, working in concert to exactly achieve a given legal sublanguage of the uncontrolled system's language model.

Synthesizing Deterministic Controllers in Supervisory Control [PDF]
, 2007 Supervisory control theory for discrete event systems is based on finite state automata whose inputs are partitioned into controllable and uncontrollable events. Well-known algorithms used in the Ramadge-Wonham framework disable or enable controllable events such that it is finally possible to reach designated final states from every reachable state ...

Blocking and controllability of Petri nets in supervisory control
IEEE Transactions on Automatic Control, 1994This 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.
