The current situation in automation is characterised by an ongoing trend towards distributed systems based on intelligent devices, the application of Web services and the usage of Ethernet as the main communication media. The most important standard to deal with distributed control systems (DCSs) is the IEC 61499 whose industrial application is still at the beginning. Within this paper, a platform...
This paper presents an implementation approach of artificial neural networks in industrial network environment, through the use of function blocks standardized by field-bus foundation (FF). This enables the implementation of a wide range of applications that involve this mathematical tool, such as intelligent control, failure detection, etc in standard FF system. For validation propose, some examples...
The paper addresses the problem of modelling a FMS with random recipes and controlling it with an agent-based architecture. One of the features of the system are the random recipes, i.e. recipes that are unknown a priori for the control system, which represent a high flexible-routing class of FMS. In particular, a PN model able to represent both the mechanism of generation of random recipes and then...
This paper discusses a new approach to the development life-cycle of agent-based production control applications, from the design to the operation, based in a catalogue of high-level Petri nets. The high-level Petri net-based approach facilitates the conception, definition and formal specification of an "encapsulation process" in industrial production systems. The catalogue includes elements...
This paper presents the SC-MER, safety control for Mars exploration rover, an innovative traction control scheme for wheeled mobile vehicles. The system is thought to be used on space mission rovers and is based on fuzzy logic and competitive neural networks to achieve optimal navigation on rough terrain with variable morphology. The main goal of this research is to minimize the power consumption...
