Abstract
A new layered architecture for the implementation of intelligent distributed control systems is proposed. This architecture distinguishes four levels in a distributed system. Upper layer consists of a digital control layer, where high level decisions are taken. This level is implemented by means of intelligent software agents and distributed expert systems that carry out the discrete control functions, system supervision as well as diagnosis and fault tolerance. Third layer deals with numeric values, performs analog operations and implement analog control loops. It is also in carry of the conversion from numerical variables values to evaluated expressions. This layer has been implemented by means of neural networks. Networking appears in the second layer, formed by CAN and Internet for content distribution. Finally, every node should implement a hardware interface with the process. Some interesting features provided by this architecture are its low-cost implementation, easy content distribution through the communication infrastructure, distributed execution in virtual generic nodes -with no hardware dependency-, bounded response time and fault tolerance mechanisms.
