The machine learning technology has been implemented in control systems successfully especially in the stochastic process. Among the machine learning algorithms, the reinforcement learning algorithm is fairly significant. On the other hand, the elevator, as a facility in daily life, is implemented with several heuristic control methods in the past practice. Simultaneously, the elevator working procedure...
New approaches and business models for the development of renewable sources are needed as an alternative to feed-in tariffs. In this work, we present a tool-chain based on a distributed infrastructure for planning renewable energy systems deployment. This solution aims at fostering new services and business models by promoting energy community actions. Such tool-chain is able to: i) evaluate the photovoltaic...
This paper presents a new type of crane system that can be employed in a narrow space in an ordinary house for supporting nursing and housework. The crane consists of straight and curved rails that can be assembled/disassembled so that an operator is able to assemble them according to the room/corridor structure of a house. Because an operator may not hold the transported person or object (load) in...
In the industrial automation a paradigm shift from centralized, static automation structures to reconfigurable manufacturing systems (RMS) might be lie ahead. RMS are seen as a key enabler for the required changeability of future production companies since they can reduce the engineering effort needed for the reconfiguration of existing or the construction of new production systems. However, it is...
This paper addresses the efficient generation of models for cyber-physical systems from large historical data sets. A cyber-physical system (CPS) is a system composed of physical subsystems together with computing and networking. CPS models are required for monitoring and control of the physical processes. Such models are in general hybrid models that take into account both discrete control signals...
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,...
This paper proposes a geographical routing algorithm based on Zone Routing Protocol (ZRP) to limit the area for discovering a new route by utilizing location information of nodes. Mobile Ad Hoc Networks (MANETs) have attracted much attention in the research and the industry. In MANETs using ZRP algorithm, nodes use Route REQuest messages (RREQs) to obtain a new route often by bordercasting them to...
The prime goal in automation systems is to increase productivity while at the same time save production costs. Nevertheless, in recent years there is increasing concern about the ecological footprint of production systems and a growing demand for energy optimization. Heating, ventilating and air conditioning (HVAC) systems in large industrial buildings consume a substantial amount of energy and typically...
In this paper, an FPGA based FIFO with efficient memory management is proposed, which allows fast forwarding of real-time Ethernet frames. There are two main drawbacks of the existing FIFO implementations with respect to the buffering of Ethernet frames. Currentness of data is not guaranteed in case of buffer overflow because the new frames are dropped in this case. Furthermore, exhaustive resources...
In order to achieve rapid development process and reduce the time to market, new approaches have been investigated for automotive body assembly design. This research presents a prospective study about using plant digital mock up to support industrialization process and design reviews. The concept of Digital Lot (DLot) is introduced as a design object to validate a layout and assembly processes alternative...

However, being ca relatively new industrial scale consumer, data center requires cmore careful consideration and research to uncover its specifics cand better understand its requirements; and investigate data ccenter's impact on regional...
Automated production systems are usually driven by Programmable Logic Controllers (PLCs). These systems are long-living and have high requirements for software quality to avoid downtimes, damaged product and harm to personnel. While commissioning multiple systems of similar type, pragmatic adjustments of the software are often necessary, which results in two or more similar variants of initially identical...
Message-based Networks-on-a-Chip (NoC) provide significant advantages with respect to temporal predictability, fault isolation and energy efficiency. However, the AUTOSAR standard for multi-core operating systems focuses only on multi-core platforms with shared memories. In order to obtain the benefits of message-based interactions, this paper maps an AUTOSAR system to a multi-core platform with a...
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...
ABB Medium Voltage (MV) drives offer flexible and reliable modular design for single as well as multi motor applications with power range from 3 to 36 MW. In order to validate the complex converter topologies and control methodologies of MV drives, a powerful multi core real time simulator is used for Hardware in Loop (HiL) testing. The Medium Voltage Drive Hardware-in-Loop (MVDHiL) system is preferred...
The protection and preservation of cultural heritage for generations is a challenging task. Therefore this paper describes a system for non-contact and safe 3D measurement and digitization of unique cultural objects and craftworks. The aim of this project is the precise 3D capturing and the semi-automated processing of smaller and medium-sized cultural objects. Therefore this paper suggests a system...
Interoperability is a key feature in today's IT-Environments. To achieve interoperability, the user's actions when connecting two different systems have to be minimized. For this reason, several service based systems have been developed. However, as far as the current implementations in the field are concerned, all of them need connectors and gateways that are individually developed to connect heterogeneous...
In nowadays Smart Grids, economic optimizations performed by Virtual Power Plants (VPPs) may interfere with stable grid operation required by Distribution System Operators (DSOs). Since Smart Grids and VPPs are important building blocks of future energy systems, bridging the gap between economic optimization performed by VPPs and stable grid operation required by DSOs is an important task. In this...
To test the control code of an automated manufacturing system, virtual commissioning (VC) can be employed: the binary input and output signals of the controller (usually a Programmable Logic Controller, PLC) are connected with a simulation model of the plant. To resemble the physical behavior of the plant and of the sensors and actuators, the simulation model is usually a mixed continuous/discrete...
This article proposes a new approach for high speed and precision motion control of feed drive systems by considering both tracking and contour errors. Iterative learning control is used whereby the tracking error is considered in the feedback controller and the contour error in the feedforward controller. Without changing the original trajectory assigned by NC code, the proposed controller improves...
