Modeling and Development of FMS (Flexible Manufacturing Systems) Control Systems Using EMMN (Extended Moore Machines Network) Model

摘要

One essential task for implementing Flexible Manufacturing Systems (FMS) at the factory level is to achieve control. This requires an appropriate control model that can be used not only as a tool for analyzing control problems, but also as a platform for control software development. The Extended Moore Machine Network (EMMN) modeling scheme is introduced using the formalism of automata theory and a distributed, bottom-up approach. The basic concept of the EMMN is to represent a complex system through a set of interconnected, abstract machines. The global behavior of an EMMN is defined as a regular language which provides the basis for discrete event control. Using object-oriented methodology, the EMMN model is implemented as a formal framework for designing and specifying FMS control software.
