Intelligent device formal description applied to hybrid systems

摘要

In this paper, the generic model, we have developped for smart instruments, is used to specify hybrid systems. The proposed model contains on one hand an external description which is the user's point of view, and on the other hand, the internal description which provides the functionalities which have to be implemented. In particular, we focuse our interest on operating modes and we compare our description with other specifications of reactive systems such as Statecharts. The classical exemple of an automobile cruise control system is used for illustration.
