This paper presents a supervisory generalized predictive control (GPC) by combining GPC with statistical process control (SPC) for the control of the thin film deposition process. In the supervised GPC, the deposition process is described as an ARMAX model for each production run and GPC is applied to the in situ thickness-sensing data for thickness control. Supervisory strategies, developed fr...

An elevator group supervisory controller is a control system that manages systematically two or more elevators in order to serve passengers as required. The elevator cars are assigned accordingly in response to hall calls, so as to optimize waiting time, riding time, power consumption, passengers’ comfort, etc. In this paper, the simplicity of ordinal structure fuzzy logic in making crucial sup...

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...
