New demands, coming from the industry 4.0 concept of the near future production systems have to be fulfilled in the coming years. Seamless integration of current technologies with new ones is mandatory. The concept of Cyber-Physical Production Systems (CPPS) is the core of the new control and automation distributed systems. However, it is necessary to provide the global production system with integrated...
The current economical situation has forced European industries to increase their competitiveness regarding production system flexibility. One of the key initiatives within this research and development process is the german “Industrie 4.0” initiative aiming on increasing flexibility and improving vertical and horizontal integration. One key element of this initiative is the “Industrie 4.0 component”,...
Aggregators are considered to be a key enabling technology for harvesting power system services from distributed energy resources (DER). As a precondition for more widespread use of aggregators in power systems, methods for comparing and validating aggregator designs must be established. This paper proposes a functional reference architecture for aggregators to address this requirement.
Many Factory Automation Systems (FASs) are been increasingly required to provide 24/7 in-service operation. This demands increasingly-higher levels of autonomy, and makes FAS control architectures include extra regulating capabilities in order to deal with long-term but also non-stop operations. Continuous assurance of effectively-coordinated adaptation to unpredictable internal and external changes...
In the last years a new computing paradigm called Internet of Things (IoT) has been gaining more attention. This paradigm has become popular by embedding mobile network and processing capability into a wide range of physical computing devices used in everyday life of many people. An important part that composes the IoT is the middleware, which is a system that abstracts the management of physical...
This paper presents an approach that uses a 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 GETEC Heat & Power AG. For this case, adaptive distributed 3-layer boiler control system with the supervisor on top is invented, supported on the middle layer with load distribution...
The pervasive use of embedded computing systems in modern societies altogether with the industry trend towards consolidating workloads, openness and interconnectedness, have raised security, safety, and real-time concerns. Virtualization has been used as an enabler for safety and security, but research works have proven that it must be extended and improved with hardware-based security foundations...
Multithreading is a key feature for dealing with the complexity of current generation embedded devices. Real-Time Operating Systems (RTOSes) provide a higher level of abstraction that alleviates design complexity and time-to-market pressure, inducing, however, undesired latencies and unpredictable execution times. Research works have been focusing on improving performance, determinism or agnosticism,...
Simulation is a tool offering several advantages in the field of automated manufacturing systems, permitting their analysis and evaluation overcoming complexity, cost, scaling, risk, and timing issues. Gamification technologies may complement limitations of conventional engineering systems towards a more natural human way of working. A gaming platform is utilized for the purpose of building an industrial...
Wireless Sensor Networks (WSNs) have been widely considered as a promising solution to support different types of applications on industrial environments. Many of these applications impose strict dependability requirements, since a system failure may result in economic losses, or damage for human life or to the environment. The absence of an effective approach enabling the dependability evaluation...
Multi-carrier approaches have arisen in the last years as a suitable medium access technique for many communications standards, such as PowerLine Communications (PLC). This one is based on using mains for data transmission, not only in industrial environments but also in public buildings, residences and houses. One of these multi-carrier solutions is based on the Filter-Bank Multi-Carrier (FBMC),...
In this paper, a genetic algorithm (GA) method for the design of the operational architecture of a control system is presented. It provides from the knowledge of some characteristics of the functions that the control system must ensure, an allocation solution of these functions on industrial controllers while satisfying capabilities, compatibility and exclusion constraints in order to minimize the...
We present our monitoring and decision framework for collaborative engineering for globally distributed operation, support, maintenance, and services for industrial automation. The framework provides relevant information to plant operators, engineers, staff and stakeholders to support the handling of incidents, based on semantically-appropriate factors such as personnel skills, physical location of...
In recent years automation systems have been required to provide characteristics of flexibility and efficiency in order to cope with the fast changes of the market and consumer demands. To deal with these requirements, the industry has started to implement reconfiguration techniques in order to allow the automation system to reschedule the production, recover from faulty situations and to update the...
The paper illustrates the research activity of a joint research laboratory, established by COMAU and Politecnico di Torino, named “RoboLAB”, and devoted to industrial robotics issues. The lab facilitates a stable cooperation between the academic and industrial partners, leading to satisfying results both from the scientific and the technological point of view. The paper illustrates in particular the...
This paper describes a whole new framework to quickly develop dynamic visual servoing systems embedded in an FPGA. Parallel design of the algorithms increases the precision of this kind of controllers, whereas minimizes the response time. Embedding dynamic visual servoing algorithms converts these systems into real-time systems. Additionally, an optimal control framework to dynamically visual control...
Building Automation Systems take care about many different kinds of automation tasks within today's buildings. The provided services are usually distributed across the related buildings, are developed by various vendors, use different communication standards, have disjunct semantic representation of data and so on. In larger, flexible and growing BAS it's obviously hard to manage all services without...
Cyber-physical systems (CPSs), due to their direct influence on the physical world, have to meet extended security and dependability requirements. This is particularly true for CPS that operate in close proximity to humans or that control resources that, when tampered with, put all our lives at stake. In this paper, we review the challenges and some early solutions that arise at the architectural...
The IoT research area has evolved to incorporate a plethora of messaging protocol standards, both existing and new, emerging as preferred communications means. The variety of protocols and technologies enable IoT to be used in many application scenarios. However, the use of incompatible communication protocols also creates vertical silos and reduces interoperability between vendors and technology...
