In this work, implementation issues related to multivariable Generalized Predictive Control (GPC) for processes with multiple time delays are analyzed. Due to specific properties of those processes, the resulting control system has to account for the existing delays between control variables changes and their effect on controlled outputs. In the case of Model Predictive Control (MPC) techniques, such as GPC, the dead-time issue can be captured in the process model and thus considered in the predictive mechanism of the controller. However, this working principle results in augmented matrix dimensions that considers input-output time delays as additional zero entries. This fact increases the computational load and has to be accounted for in the control system design, specially in systems where computing resources are scarce (eg. embedded systems). The reduction of the matrix dimension, and hence the computation required, depends on how the delay terms are structured. The presented analysis considers two different GPC implementations for multivariable dead-time processes, which are used to compensate for internal matrix dimensions for the multiple time delays. Each implementation mode is evaluated for two industrial multivariable processes, providing several performance indexes. Performed simulations show that the required computational load can be reduced when adequate implementation mode is selected.

The digitalization and its corresponding technologies have a fundamental impact on value creation strategies and business models of companies across different industries, including the manufacturing and automation industry. The emergence of complex and dynamic ecosystems is one of the expected impacts. The present research project will analyze the business models of ecosystems in the manufacturing industry in the upcoming project phase. To enable this analysis, we generated two intermediate products which will be presented in this article: A role model of the manufacturing industry and the identification of key digitalization technologies and their application. The role model consists of 25 roles and builds on the model of interlinked value creation processes for Industrie 4.0 by the German VDI/VDE societies. The research on the digitalization technologies revealed the key ten digitalization technologies and identified patterns in the application of those technologies in real use cases.

Programming industrial robots requires experts -not only to create the robot applications, but also for changing them later due to different product requirements. Part of the reason for this is that all robot vendors provide their own robot programming language. Due to the language differences, robot applications cannot be reused for different robot types. Often, additional experts are required since one expert is trained only for a special robot type. This makes the use of robots uneconomical for small and medium sized enterprises. The ReApp project addresses this problem by providing a workbench based on ROS (Robot Operating System). A central part of this workbench is the skill and solution modeling tool, which allows the model-based design of robot applications composed of reusable components, and is described in this paper.

Cash machines or automated teller machines (ATMs) are one of the typical ways to get cash around the world. Such machines are under a variety of criminal attacks. Most of the manipulations are performed through skimming. In 2014, such attacks led to a damage of approx. 280 million Euro within the EU. In this paper, we propose an approach to detect anomalies and attacks on ATMs via motif discovery. Motifs are frequently unknown occurring sequences or events in a time series signal. State of the ATM is captured by innovative piezoelectric sensor networks to analyse the occurring vibrations. The captured signals are inspected by the Complex Quad-Tree Wavelet Packet transform which provides broad frequency analysis of a signal in various scales. Next, features are extracted from the selected scale based on the information content, to detect motifs. Detected motifs provide the prototype patterns for anomaly detection or classification tasks.

The lack of efficient and intuitive programming paradigms for industrial manipulators stands in the way of increasing the degree of automation in various industrial manufacturing environments. We approach this lack by exploring tactile surface sensors (TSS) enclosing the links of a manipulator as a gesture input device for intuitive robot programming. First, our low-cost tactile surface sensor is briefly presented. Subsequently, a preliminary gesture set is introduced and feature-based approaches for gesture recognition are addressed. Furthermore, the extraction of relevant parameters from the gestures as well as the integration of gesture input into our skill-based robot control architecture are outlined. Quantitative performance results based on a user study with 12 subjects and a set of 7 gestures show that even with a comparatively low spatial resolution of the sensor (20mm) average accuracies of over 90% can be obtained.

In the recent decade, many formalisms and tools have emerged for model-driven Non-Functional Property (NFP) specification and assessment. In this direction, model-driven reliability and safety assessment of engineering systems developed using Matlab/Simulink is an emerging research challenge. However, a generic mechanism for NFP specification in the Simulink design model is not yet supported. Further, a completely automated model-based workflow for synthesis of a NFP analysis model and its subsequent analysis in a NFP analysis tool is missing. In this context, this paper proposes a novel approach and a fully automated workflow towards model-driven reliability analysis of Simulink models. An approach to annotate the Simulink design models with reliability attributes and subsequent synthesis of fault trees from the annotated design model is described. A prototype and initial experimental results are discussed.

Model-based development (MBD) has become important in the automobile domain. Automobile control systems consist of various software applications, and with MATLAB/Simulink, developers can design such applications using synchronous reactive models represented by synchronous block diagrams (SBD). The automotive open system architecture (AUTOSAR), a global development partnership formed to create open and standardized software architecture for automotive electronic control units (ECU), can provide highly reusable middleware. In this case, developers must map blocks of the SBD to AUTOSAR runnables, i.e., ECU processing units, and then assign the runnables to the ECUs. Most sample models are single-rate models. However, multi-rate control models will become essential due to the increasing complexity and scale of such automotive systems. This paper proposes top-down mapping algorithms from multi-rate control SBDs to runnables in consideration of schedulability, modularity, and code size. Note that proposed algorithms do not consider reusability. Evaluation results demonstrate that algorithms provide runnable sets with superior modularity than an existing algorithm.

Future vehicles will be wirelessly connected to nearby vehicles, to the road infrastructure and to the Internet in order to enable new comfort features, safety functions and a number of new vehicle-specific services. The latter will include a fast, secure, and reliable way to remotely diagnose and reconfigure a vehicle as well as to install new software on the electronic control units integrated in a vehicle. Such wireless software updates are beneficial for both automotive OEMs and customers, as they allow to enable new features of the vehicle remotely and to fix software bugs by installing a new software version over the air. Wireless diagnostics and software updates are required in several stages of a vehicle's lifetime: from the manufacturing stage on the assembly line and the maintenance in a workshop to the remote download of up-to-date software directly by the car owner. To support this process over a whole vehicle's lifetime, a generic framework is needed. In this paper we propose a generic framework enabling secure and efficient wireless automotive SW updates and hence supporting a vehicle's whole lifetime. We describe the IEEE 802.11s network used as wireless medium to interconnect vehicles and diagnostic devices in a reliable, trustworthy and fast way and propose a dedicated cross-layer security concept applying strong authentication as well as encryption mechanisms.

Due to the possibility of extensive and pervasive deployment of many tiny sensor devices in the area of interest, Wireless Sensor Networks (WSNs) result particularly suitable to detect significant events and to react accordingly in industrial and home scenarios. In this context, fuzzy inference systems for event detection in WSNs have proved to be accurate enough in treating imprecise sensory readings to decrease the number of false alarms. Besides reacting to event occurrences, the whole network may infer more information to enrich the event semantics resulting from reasoning processes carried out on the individual nodes. Contextual knowledge, including spatial and temporal relationships, as well as neighborhood confidence levels, can be used to improve the detection accuracy, but requires to extend the number of variables involved in the reasoning process.

The way how we interact with banknotes is changing. This raises questions on how we interact with electronic payment systems. The general idea is to design low-cost electronics for cash handling systems. We establish a prototypical demonstrator which allows a consistent image capture quality and is able to handle complex algorithms for banknote authentication on cost-effective hardware. Therefore, tasks regarding reducing the evaluation time, without diminishing the reliability of the algorithms have to be considered. In this contribution we focus on the re-design of an authentication module for detection of commercial offset printing. This module analyses images in view to periodic printing patterns by means of the Discrete Fourier Transform (DFT). We propose to implement two concepts: an adaptive software architecture for DFT and parallel image processing. The re-design reduces evaluation time, without compromising the reliability of the authentication algorithm.
