Automata Based Modeling for Batching and Mixing Plants for Concrete

This paper deals with the modeling of a batching and mixing plant for concrete. Such plants are hybrid systems since they are described by both discrete and continuous variables. For building system model, a recently proposed hyper-class of hybrid automata was used. This method provides greater modeling power compared with conventional methods, being suitable for modeling analysis of a wider variety of systems. The model described entails a hierarchical model with an automaton as supervisor and several other automata controlling each system´s part.
