due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. this paper employs modified petri nets (mpn) to model theses subsystems and makes it simple to analyze them. in this method, first, the continuous transfer function is converted to a discrete transfer function and then, by mpn, system is modeled and analyzed. all...

 Loyalty is the process of arising as a result desire to faithfully and serve either on its work, group, boss his company, this led someone willing make sacrifices for sake satisfying other parties or public. Design research cross-sectional. The sample was 74 managing nurses who worked in inpatient room RSU Partners Medical Medan. Test results showed bivariat between supervision w...

PaZriciai E. Ropis, MSN, RN, is an Assistant Prof~ssor, Department of Nursing, Seton btall University, South Orange. NJ. S tress is pandemic in today's society. Results of an occupational stress survey in the early 1990s (Northwestern National Life, 1991) showed that the proportion of workers who reported feeling "highly stressed" Inore than doubted between I985 and 1990 (Speill~erger & Vagg, 1...

Because of their nondeterministic nature of behaviour, the supervisory control of manufacturing systems must be carried out in closed loop. This trait greatly increases the size and complexity of the Discrete-Event System (DES)-based supervisorycontrollers of manufacturing systems. Attempting to cope with this complexity, a Hybrid Supervisory Controller (HSC), that distributes operations betwee...

The seminal work on theory of Supervisory control in Discrete Event Systems was pioneered by Ramadge and Wonham. Taking inspiration from this work, extensive research has been done to extend the theory to real-time. The main problem in the research related to real-time supervisory control is that theories of RW framework are not directly applicable because of infiniteness of state space. This p...

In this paper, the supervisory control synthesis of modular or distributed discreteevent systems is discussed. The coordination-control architecture proposed by Komenda and van Schuppen (2008) and studied for prefix-closed specification languages by Komenda et al. (2010a,b) is generalized to the case of non-prefix-closed global specification languages and non-prefix-closed plant languages. Nece...

This work focuses on the design of a supervisory predictive control system for the optimal management and operation of a stand-alone wind-solar energy generation system which provides power to a reverse-osmosis (RO) water desalination system. We design the supervisory control system via model predictive control which coordinates the wind and solar subsystems as well as a battery bank to best sa...

We present a formal connection between supervisory control theory in the field of control engineering and reactive synthesis in the field of formal methods. We focus on the case of fully-observed discrete-event systems that are controlled by a single controller/supervisor in order to achieve a safety specification and a non-blocking specification. The connection is shown by a reduction of the c...

The paper presents sufficient conditions for modular (supervisory) control synthesis to equal global control synthesis. In modular control synthesis a supervisory control is synthesized for each module separately and the supervisory control consists of the parallel composition of the modular supervisory controls. The general case of the specification that is indecomposable and not necessarily c...
