An object-oriented interface for control and automation software in open architecture systems

A unified framework for control system and automation software design is proposed. Under this framework, a supervisory synthesis methodology with DES specification can be used in designing control software not only for a single machine but also for machines' integration. In the structural design, basic classes of our proposed framework are modelled by object-oriented analysis (OOA) and design techniques presented by the UML (Unified Modeling Language) notation. Secondly, in the mechanistic design, a design pattern is used to improve the modality and flexibility of the framework. Finally, a distributed object technique using CORBA is used for implementation, and a simple example is presented.
