A diagnosis of the actual distributed control and measurements system for a Teniente Converter, processing copper concentrates is presented. Besides the importance of this converter in Caletones Smelter, there are a number of unsolved problems related to lack of instrumentation, lack of process knowledge, odd operating practices, and in general lack of use of procedures to process data to aid m...

This paper presents an approach that uses supervisor architecture structure with the intention to reach flexibility of the combustion process control during the boiler functioning on the example of the high qualified Power AG. For this case, adaptive distributed control system with the supervisor on top is invented, on the middle layer with load distribution on burners and maintenance of optima...

An Evolutionary Algorithm (EA) strategy for the optimization of generic Work-In-Process (WIP) scheduling fuzzy controllers is presented. The EA is used to tune a set of fuzzy control modules which are used for distributed and supervisory WIP scheduling. The distributed controllers objective is to control the rate in each production stage so that satisfies the demand for final products while red...

In this paper we present the rst results of our attempt to set up a supervisory theory for nondeterministic discrete event systems. The supervisory control problem for nondeterministic systems is speciied and motivated. A necessary and suucient condition for the existence of a supervisor is derived. Also an algorithm is presented that will automatically generate a supervisor. The results are ex...

A third of the Dutch highways is monitored and controlled by roadside units. These RSUs are safety-critical systems, as they safeguard roadworks accidents. Therefore, it essential to have guarantees on correctness unit controller. Using supervisory control theory, a correct-by-construction supervisor obtained from model system its requirements. From model, controller implementation can be autom...

This paper describes the supervisory control of mobile robots using a biologically inspired short-term memory structure called a Sensory EgoSphere. The EgoSphere is implemented as a virtual geodesic dome upon which sensory data from the surroundings of the robot are written. The EgoSphere is managed by a distinct agent in a distributed agent-based robot control architecture called the Intellige...

The recent production technologies reflect a worldwide trend towards both, batches of small and medium size, and part families of increasing variety. This tendency often comes in conflict with the demand on high productivity and on simultaneous improvement of machine utilization. Flexible production systems (FPS) possess the ability to attain efficiency and versatility by producing a wide range...

Supervisory control and data acquisition systems (SCADA) are widely used in industry for supervisory control and data acquisition of industrial processes. The process can be industrial, infrastructure or facility. With the advances of electronic and software technologies, the SCADA systems are widely used in industrial plant automation. It provides an efficient tool to monitor and control equip...

This article proposes a novel, web-based, remote monitoring and control system design for a building’s electrical power, green power generation and environmental system that will save energy. The supervisory control system is based on the use of distributed microcontroller architecture to access programmable logic controllers (PLC) and remote input/output devices through the system hardware fra...
