Conference paper (peer-reviewed)abstract
- In this paper, a distributed home automation system will be demonstrated. Traditional systems are based on a central controller where all the decisions are made. The proposed control architecture is a solution to overcome the problems such as the lack of flexibility and re-configurability that most of the conventional systems have. This has been achieved by employing a method based on the new IEC 61499 function block standard, which is proposed for distributed control systems. This paper also proposes a wireless sensor network as the system infrastructure in addition to the function blocks in order to implement the Internet-of-Things technology into the area of home automation as a solution for distributed monitoring and control. The proposed system has been implemented in both Cyber (nxtControl) and Physical (Contiki-OS) level to show the applicability of the solution

An ontology-based reconfiguration agent for intelligent mechatronic systems
- 2007
-
In: Holonic and multi-agent systems for manufacturing. - Berlin : Encyclopedia of Global Archaeology/Springer Verlag. - 9783540744788 ; , s. 114-126
-
Conference paper (peer-reviewed)abstract
- This paper discusses an ontology-based reconfiguration agent that uses ontological knowledge of the manufacturing environment for the purpose of reconfiguration without human intervention. The current mass customization era requires increased flexibility and agility in the manufacturing systems to adapt changes in manufacturing requirements and environments. Our configuration agent minimizes the overheads of the current reconfiguration process by automating it. It infers facts about the manufacturing environment from the ontological knowledge model and then decides whemer the current environment can support the given manufacturing requirements

Conference paper (peer-reviewed)abstract
- This paper discusses the extension of an ontology-based reconfiguration agent that uses ontological knowledge of the manufacturing environment for the purpose of reconfiguration without human intervention. The current mass customization era requires increased flexibility and agility in the manufacturing systems to adapt changes in manufacturing requirements and environments. Our configuration agent minimises the overheads of the current reconfiguration process by automating it. It infers facts about the manufacturing environment from the ontological knowledge model and then decides whether the current environment can support the given manufacturing requirements. This paper proposes an extension of the agent architecture enabling the integration between the high level planning with the distributed low level control compliant with the upcoming IEC 61499 function blocks standard

On Achieving Reliable Communication in IEC 61499
- 2018
-
In: 2018 IEEE 23RD INTERNATIONAL CONFERENCE ON EMERGING TECHNOLOGIES AND FACTORY AUTOMATION (ETFA). - Piscataway, NJ : IEEE. - 9781538671085 ; , s. 147-154
-
Conference paper (peer-reviewed)abstract
- This paper proposes a novel extension for communication in the IEC 61499 standard. Inspired by the features found in the formal programming language SystemJ, the extension supports reliable and guaranteed communication in distributed execution of function block application(s)/program(s). The extension utilizes mechanisms agnostic on underlying network protocols and are based on formal semantics that guarantee data delivery. The use of proposed extension, called channel, is demonstrated in an industrial automation-type example.

A Design Pattern for Systems Composed from Intelligent Mechatronic Modules with Wireless Communication
- 2019
-
In: Proceedings. - : IEEE. ; , s. 41-48
-
Conference paper (peer-reviewed)abstract
- This paper presents a software design pattern for systems composed from distributed intelligent mechatronic modules which communicate with each other via wireless interface. The design pattern is formed by integrating the reliable communication mechanism called channel, which comes from a system-level programming language SystemJ. The paper demonstrates how the design pattern can be applied in an industrial automation example.

Digital Twin-Assisted Controlling of AGVs in Flexible Manufacturing Environments
- 2021
-
In: 2021 IEEE 30th International Symposium on Industrial Electronics (ISIE). - : IEEE.
-
Conference paper (peer-reviewed)abstract
- Digital Twins are increasingly being introduced for smart manufacturing systems to improve the efficiency of the main disciplines of such systems. Formal techniques, such as graphs, are a common way of describing Digital Twin models, allowing broad types of tools to provide Digital Twin based services such as fault detection in production lines. Obtaining correct and complete formal Digital Twins of physical systems can be a complicated and time consuming process, particularly for manufacturing systems with plenty of physical objects and the associated manufacturing processes. Automatic generation of Digital Twins is an emerging research field and can reduce time and costs. In this paper, we focus on the generation of Digital Twins for flexible manufacturing systems with Automated Guided Vehicles (AGVs) on the factory floor. In particular, we propose an architectural framework and the associated design choices and software development tools that facilitate automatic generation of Digital Twins for AGVs. Specifically, the scope of the generated digital twins is controlling AGVs in the factory floor. To this end, we focus on different control levels of AGVs and utilize graph theory to generate the graph-based Digital Twin of the factory floor.

Hybrid Digital Twin for process industry using Apros simulation environment
- 2021
-
In: 2021 26th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA). - : IEEE.
-
Conference paper (peer-reviewed)abstract
- Making an updated and as-built model plays an important role in the life-cycle of a process plant. In particular, Digital Twin models must be precise to guarantee the efficiency and reliability of the systems. Data-driven models can simulate the latest behavior of the sub-systems by considering uncertainties and life-cycle related changes. This paper presents a step-by-step concept for hybrid Digital Twin models of process plants using an early implemented prototype as an example. It will detail the steps for updating the first-principles model and Digital Twin of a brownfield process system using data-driven models of the process equipment. The challenges for generation of an as-built hybrid Digital Twin will also be discussed. With the help of process history data to teach Machine Learning models, the implemented Digital Twin can be continually improved over time and this work in progress can be further optimized.

Towards a 3D Scanning/VR-based Product Inspection Station
- 2020
-
In: Proceedings. - : IEEE. ; , s. 1263-1266
-
Conference paper (peer-reviewed)abstract
- Quality control of products plays an important role in various stages of the manufacturing process. In particular the final control of the quality of a product before being shipped to a customer is crucial for maintaining customer satisfaction and avoiding costly recalls. Automating quality inspection and integrating it into a seamless Industry 4.0 setting is therefore an important topic in factory automation.We present early work towards an automated product inspection station. Our inspection station features a 3D scanner as well as a Virtual Reality headset for remote human inspection. In addition, our concept provides for automated analysis of scans in the cloud. We present an architectural concept as well as an early prototype.
