This paper presents a new approach to power system automation, based on distributed intelligence rather than traditional centralized control. The paper investigates the interplay between two international standards, IEC 61850 and IEC 61499, and proposes a way of combining of the application functions of IEC 61850-compliant devices with IEC 61499-compliant “glue logic,” using the communication services...
This paper presents a new approach to modelling automation systems based on the combination and mutual transformation of IEC61499 Function Blocks and MATLAB Simulink. The reason for such transformation is the natural complementarity of these two models: MATLAB Simulink/Stateflow provides a nice environment for modelling and simulation of control and embedded systems, while Function Blocks are good...
This paper presents an overview of the works on design and validation of distributed control in process industry. Due to the significant market demand for distributed reconfigurable systems, not just in manufacturing industry but also in process industry, several researches are undertaken to look at the design techniques in implementation of such a decentralized control approach. It has shown that...
This paper addresses solutions on integration and reuse of heterogeneous distributed controllers. In particular it shows the way to integrate the emerging IEC 61499 standard into the established IEC 61131 automation frameworks. It is illustrated on example of a modular manufacturing cell with distributed control units, how to realize distribution of heterogeneous controllers using the IEC 61499 standard...
This paper presents a case study on the use of the IEC 61499 reference component architecture in automotive electronics that is a traditional domain of embedded systems application. The proposed design approach allows for combination of distributed embedded control with off-line and on line simulation. The benefits of the approach are: the higher level of design leading to the increased level of component...
This paper describes formal modeling and verification of automation systems from the system engineering point of view. Reuse of model components is the key issue in order to bring the scientific modeling methodology into engineering practice. The reuse is achieved by the combination of modular modeling of automation systems with object-oriented description of models in UML style. This allows to benefit...
