In our previous work, a communication protocol for the reliable communication of discrete event supervisors that are implemented on physically distinct controller devices on a shared-medium network was developed. Here, the required data exchange is captured by communication models that are algorithmically computed from an underlying hierarchical and decentralized supervisor synthesis. These communication models are particularly efficient if all synthesized supervisors are implemented on distinct controller devices. In this paper, the general case is considered, where multiple supervisors can be aggregated on each controller device. To this end, the algorithmic communication model computation is adapted in order to remove communication among supervisors on the same controller device. The benefit of the controller aggregation is illustrated by a manufacturing system case study.

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...
Cooperative relaying schemes for narrow-band frequency hopping wireless ad hoc networks Yenihayat, Güven; Onat, Furuzan Atay; Kolaǧasioǧlu, Ertuǧrul; Yılmaz, Ali Özgür (2011-08-29) Cooperative relaying is a promising technique for improving the performance of weak communication links in wireless networks by exploiting spatial diversity induced by relay transmissions. This paper considers cooperative relaying schemes for a narrow- band frequency hopping system. A novel hybrid relaying scheme called opportunistic hybrid relaying, which is specifically designed for this system, is presented. Unlike most relaying schemes in the literature, opportunistic hybrid relaying uses bandwidth effi...
Communication of distributed discrete-event supervisors on a switched network Schmidt, Klaus Verner; Schmidt, Şenan Ece (2008-05-30) In order to tackle the controller synthesis problem for large-scale discrete-event systems, recent approaches suggest the design of interacting modular or decentralized supervisors. In these works, information exchange between the supervisors is either required implicitly by the synchronization of shared events or explicitly by the communication of events or symbols. However, it is not discussed how the communication can be realized if the supervisors are implemented in distributed controller devices that a...
Message Scheduling for the FlexRay Protocol: The Static Segment Schmidt, Klaus Verner; Schmidt, Şenan Ece (Institute of Electrical and Electronics Engineers (IEEE), 2009-06-01) In recent years, time-triggered communication protocols have been developed to support time-critical applications for in-vehicle communication. In this respect, the FlexRay protocol is likely to become the de facto standard. In this paper, we investigate the scheduling problem of periodic signals in the static segment of FlexRay. We identify and solve two subproblems and introduce associated performance metrics: 1) The signals have to be packed into equal-size messages to obey the restrictions of the FlexRa...
Diversity Analysis of Hierarchical Modulation in Cooperative Communication Yalcin, Ahmet Zahid; Yüksel Turgut, Ayşe Melda (2014-01-01) In cooperative communication systems, hierarchical modulation is used to increase systems robustness and to send different information flows simultaneously. In cooperative communication systems which use hierarchical modulation, error propagation is the most important problem that prevents achieving full diversity gain. Thresholds that depend on the signal to noise ratio (SNR) value between the source and the relay can be used to mitigate error propagation. If the instantaneous SNR between the source and th...
