INTEGRAL AUTOMATION OF INDUSTRIAL-COMPLEXES BASED ON HYBRID SYSTEMS

The aim of this work is to present a modeling scheme for the control o f industrial complexes of continuous plants. Processes have interactio ns among them. For this purpose the paper presents a theoretical suppo rt of a generalized three level Hybrid Control model and the way to ac hieve its implementation. The superior level is a supervisor for a Dis crete Event Dynamic System while the lower level performs the control for the process units in a Continuous/Discrete Event Dynamic System. T he paper shows the interface between the continuous and discrete syste ms and the supervision via optimization of the whole plant in a multi- level, multi-modeled complex of process units.
