This paper presents the application of discrete event system in the field of power system. In power system there are various components which required control and coordination when they are in operation. The theory of discrete event system has been applied in the application part of power system. The discrete nature of ULTC and discrete switching behavior of SVC are best suited for the supervis...

We present a hierarchical control theory for supervisory automata based on state aggregation. Conditions are determined on state partitions which ensure that the control of transitions between blocks in a high level (i.e. aggregated) model, combined with local state-dependent controls, is eeective in the sense of achieving speciications given either for the high level model or for the low level...

This paper aims at developing hierarchical control architecture for continuous-flow simulation in order to regulate production in multiple-part-type flow shops. The approach uses a continuous-flow approximation to model the discrete flow of parts in a manufacturing system. The control strategy specifies how to allocate limited system capacity among all the part types to follow the solution of t...
