In this paper, we extend the results to a class of controlled Petri net with uncertainties and flexible routes (CPNU-FR). By exploiting the routing flexibility of a CPNU-FR, we characterize a feasible condition to maintain production for a certain type of products by keeping the liveness of a cyclic production route. Based on this condition, we propose a structural decomposition method to test the feasibility of production routes. Based on the liveness condition for the nominal CPN, we characterize a condition to test whether a certain type of resource failures is tolerable.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

Utilities are currently exploring methods of increasing the reliability of the power supply due to the growing number of sensitive loads. Therefore, this paper explores the impact of a series resonant fault current limiter (FCL) on the improvement of power quality of a radial distribution system. It provides simulations of a typical distribution system with and without the FCL to determine its effect on voltage dips during faulted conditions. It also investigates the interaction of the FCL with system protection and provides protection engineers with methods of re-coordinating the protective scheme after placing the series resonant FCL into a distribution system.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

We present the use of sunlight spectral measurements to estimate the composition of satellites exterior surface. We simulate the sunlight spectrum after reflection on a satellite surface by using real spectral measurements from 14 different materials commonly used on satellite surface. Several methods have been developed and tested: a linear constrained estimator and method based on the singular value decomposition (SVD) of the material database. The constrained estimator gives the best estimate regarding the presence of materials in the synthetic spectrum and regarding the relative quantity of the materials in the spectrum when both methods detect the correct materials present in the synthetic spectrum.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

However, current VSC design method leads to chattering due to the discontinuous control action involved. How to eliminate the undesirable chattering in VSC has been an interesting yet challenging topic of research. Most existing methods for chattering elimination are achieved at the price of control precision. In this paper, a new approach is introduced to remove chattering without sacrificing control precise. The idea behind the proposed approach is extremely simple: instead of designing the control input directly, the control (compensating) rate is designed. Once the rate of the compensating unit is determined, the control input is readily obtained via integration. It is shown that such a treatment leads to bounded and smooth control action while at the same time maintains asymptotical system stability. Simulations on heading speed control of flight vehicle verify the effectiveness of the method.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

The former addresses problems with initially available jobs, deterministic processing times and available machines throughout the scheduling horizon; the latter has problems with random job arrivals, non-deterministic processing times and unpredictable events such as machine breakdowns. This paper presents a complete multiple agents' framework for reactive job shop scheduling. It provides a theoretical justification that this approach is actually a completely reactive scheduling approach combining real time decision making with predictive decision making and can resolve various disruptions as flexibly as dispatching rules. The justification also includes solution schemes for dynamic job arrivals, which make full use of available information for further scheduling robustness enhancement.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

Previously, the size and operation of the power systems were considerably small and centralized compared to the large, decentralized power systems of the present day. Each discrete event occurring in the power system was manually acknowledged and necessary changes were made in the system operation. But with the recent deregulation, the sizes of the power system have increased rapidly and it is becoming very difficult if not impossible to use the traditional methods. Specialized tools are necessary for modeling and analysis of the discrete events occurring in the power system. A number of formal languages, including Petri nets and finite state machines can be used for this purpose. This paper describes how Petri nets can be used for modeling and analysis of the discrete events occurring in a power system.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

Consequently, the transmission system is becoming increasingly more constrained resulting in reduced import capability, heavily loaded lines, and stability problems. Any effort to reduce transmission congestion may provide benefits in customer choice and economic efficiency in power operation, but it will also provide new challenges for bulk-power system reliability. As generation continues to increase in localized areas, export limits will be encountered initially in the form of thermal constraints on transmission lines. Continuing to add generation into a constant effective system impedance will threaten a system stability limit. The focus of this paper is on developing proper pricing signals that may encourage generator operation in ways favorable to power system security. The well-developed locational marginal pricing concept is adopted as a basis and expanded to include constraints associated with system stability.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.
