The paper extends previous work, where we develop a control theory for nonblocking hierarchical control of decentralized discrete event systems (DES). The results are based on two technical conditions for the hierarchical abstraction: it has to be (i) locally nonblocking and (ii) marked string accepting. In this paper, we investigate the systematic construction of the hierarchical abstraction. Starting from an initial natural projection which need not fulfill (i) and (ii), we provide an algorithm to compute the hierarchical abstraction with the coarsest equivalence kernel finer than that of the initial natural projection, and such that (i) and (ii) hold. Our approach extends the work in [10], where the authors compute observers for the hierarchical control of DES.

Hierarchical multitasking control of discrete event systems: Computation of projections and maximal permissiveness Schmidt, Klaus Verner; Cury, José E.r. (null; 2010-12-01) This paper extends previous results on the hierarchical and decentralized control of multitasking discrete event systems (MTDES). Colored observers, a generalization of the observer property, together with local control consistency, allow to derive sufficient conditions for synthesizing modular and hierarchical control that are both strongly nonblocking (SNB) and maximally permissive. A polynomial procedure to verify if a projection fulfills the above properties is proposed and in the case they fail for a g...
Maximally Permissive Hierarchical Control of Decentralized Discrete Event Systems SCHMİDT, KLAUS WERNER; Schmidt, Klaus Verner (2011-04-01) The subject of this paper is the synthesis of natural projections that serve as nonblocking and maximally permissive abstractions for the hierarchical and decentralized control of large-scale discrete event systems. To this end, existing concepts for nonblocking abstractions such as natural observers and marked string accepting (msa)-observers are extended by local control consistency (LCC) as a novel sufficient condition for maximal permissiveness. Furthermore, it is shown that, similar to the natural obse...
Nonblocking hierarchical control of decentralized des Schmidt, Klaus Verner; Moor, Thomas (null; 2005-12-01) This work considers a hierarchical control architecture for a class of discrete event systems which can also be applied to decentralized control systems. It is shown that nonblocking supervisory control on the high level of the hierarchy results in nonblocking and hierarchically consistent control on the low level. Copyright © 2005 IFAC.
Hierarchical discrete event systems with inputs and outputs Perk, Sebastian; Moor, Thomas; Schmidt, Klaus Verner (null; 2006-12-01) We propose a framework for the hierarchical design of discrete event systems that addresses both safety and liveness properties. Technically, we build on a notion of inputs and outputs that is closely related to J.C. Willems' behavioural systems theory. We develop a structural admissibility condition that allows for abstraction-based controller synthesis similar to previous work on hybrid control systems. A key feature of our framework is an alternation of subsystem composition and controller synthesis that...
Hierarchical and decentralized multitasking control of discrete event systems Schmidt, Klaus Verner; Cury, José E. R. (2007-12-01) In this paper, a hierarchical and decentralized approach for composite discrete-event systems (DES) that have to fulfill multiple tasks is elaborated. Colored marking generators that can distinguish classes of tasks are used as the system model, and a colored abstraction procedure as well as sufficient conditions for nonblocking and hierarchically consistent control are developed. It is shown that the computational complexity for supervisor computation is reduced. A flexible manufacturing system example dem...
