Nowadays, it is well recognized that flexibility, modularity and reconfigurability are the main challenges in the design of manufacturing systems. Automated warehouse systems play a key role in such systems and are currently controlled using hierarchical and centralized control architectures and conventional automation programming techniques. In this paper, we present preliminary results in developing a flexible, modular and distributed control architecture for automated warehouse systems using Function Blocks and a cyber-physical system perspective. The implementation can be carried on by both IEC 61131 and IEC 61499 standards.

Localization and asset tracking are key components of the Internet of Things or the fourth industrial revolution called “Industry 4.0”. Current systems using GPS signals cannot be used indoors. Alternative systems for indoor localization exist, but they cannot be battery power with tiny batteries over multiple years. To overcome these drawbacks we propose a new localization concept based on an ultra-low-power wake-up receiver. With a power consumption of less than 10μW the tags mounted on the assets are able to operate for multiple years using tiny coin type batteries. Nevertheless, out system concept can achieve an accuracy down to the sub-meter range. This goal is reached by means of beacon based field strength localization for the indoor environment, and angle-of-arrival estimation for the outdoor environment. An additional benefit of our wake-up receiver concept is the overall low latency.

In this paper, we present a comparison between several statistical discriminant analysis techniques applied to a plastic injection moulding process for monitoring quality of injected moulded parts. Comparison among different ways of training the system can provide useful conclusions about the behaviour of the different models in poor conditions. The goal of this paper is to establish a baseline for comparing the performance between different algorithms. A wide variety of research objectives throughout the literature makes it difficult to provide a feasible comparison between results. The evaluation is intended to provide detailed, empirical information on the effectiveness and impact of different model parameters on the performance of the different approaches. The pros and cons of the approaches used are discussed. In order to predict the quality of a plastic part, we extract a set of salient features that characterise an injection cycle and then match these features against a database of stored examples of predefined classes by using supervised classification. The database was created from 199 real plastic injections without any overlap between training and testing datasets.

This paper deals with a comparative analysis of different pick & place strategies. The purpose is to give some rules to obtain a good sizing in terms of components (number of robots, conveyor speed) and control laws (individual scheduling rules of each robot, collaborative strategy of all the robots) of a multi-robot cell. This approach is validated by the use of a new simulation tool combining a behavioral simulation of multiple robots and the product flows. This simulation tool takes into account not only the end effector, but also the robots collaborative aspect to ensure the desired overall performance for a given task.

In this paper an approach for controlling overhead cranes by avoiding oscillations is proposed and experimentally tested. In particular, a dynamic inversion technique is applied to the overhead crane model to design suitable (position or velocity) set-point and torque feedforward signals. The inversion approach is further simplified in order to make the proposed methodology more industrial-oriented. Experimental results, obtained by using a scaled overhead crane built by using only off-the-shelf components, show the effectiveness of the proposed methodology.

During the past few years, with the fast development and proliferation of the Internet of Things (IoT), many application areas have started to exploit this new computing paradigm. An interesting use of IoT is in the Industrial field, which has resulted in a new business concept called IIoT (Industrial Internet of Things). Another important fact is the number of active computing devices has been growing at a rapid pace in IoT environments around the world. Consequently, a mechanism to deal with this different devices has become necessary. Middleware systems solutions for IoT have been developed in both research and industrial environments to supply this need. However, discover, search, select, and interact with devices remain a critical challenge. In this paper we present COBASEN, a software framework composed of a Context Module and a Search Engine to address the research challenge regarding the discovery and interaction with IoT devices when large number of devices with overlapping and sometimes redundant functionality are available in IoT middleware systems. The search engine of the COBASEN operates based on the semantic characteristics of the devices, which is provided by the context module, and that helps users in their interactions with desired devices. The main goal of this work is to highlight the importance of a context-based search engine in the IoT paradigm and to provide a solution that addresses the proper management of search and usage in IoT middleware environments. We developed a tool that implements all COBASEN concepts. However, for preliminarily tests, we made a functional evaluation of the search engine in terms of performance for indexing and querying response time. Our initial findings suggest that COBASEN provides important approaches that facilitate the development of IIoT applications, which based on the COBASEN systems support, may perform essential roles to improve industrial processes.

The integration of new technologies in existing work tasks requires the integration of the users in all steps of the development process. In this work the human-centred design process according to the ISO 9241-210 is applied to fulfil the necessary participation of users. The Head Worn Display Glass of Google Inc. prototypically is used to improve the periodical calibration of the driver assistance system testing bay of the AUDI A8 production line. Therefore the users where observed and interviewed during the performance of the calibration and furthermore highly integrated in the iterative design process of the user interface, the human computer interaction and the program flow. At the end a final prototype could be tested.

In this work, a practical evaluation of the filtering method for weighing system is provided. The analyzed system form a part of the horticultural fruits sorting machine, which requires a fast and reliable weight measurements. Dynamic weighing of moving objects requires fast and adaptive signal processing techniques in order to guaranty a timely response. Thus, applied signal filtration technique must ensure that the constant component remains free of noise, transient responses of load cell as well as mechanical vibrations. In this paper fast nonstationary filtering method is applied, providing optimal tradeoff between response time and settling time of steady state value. The implementation method uses the distributed approach, where an intelligent sensor captures raw signal and applies adaptive filter. Subsequently, obtained value is transmitted to central unit, that applies weight compensation function to improve the measurement accuracy. All presented results use the real signal acquired in industrial conditions from the tests of sorting machine prototype. The analyzed approach obtains promising results for all sorting modes. Moreover, classical filtering approach is used for comparison purposes and performance evaluation.

Recently, the industrial wireless protocols have been widely used around the world. However, the unreliable communication media between the sensors and the central controller renders the wireless signal channel vulnerable to many attacks. Various efforts have been devoted to study the influence of specific malicious attacks from the aspect of theoretical investigation based on different assumptions. This paper focuses on verifying the optimal Denial-of-Service (DoS) jamming attack strategy on a class of wireless industrial control system from the view of experiments. We first introduce typical control system model and DoS attack model, and an optimal DoS attack schedule against LQG control based on these models. Then, we establish a semi-physical security testbed which consists of virtual plant, physical controller and communication process. We also realize wireless DoS attacks by exploiting the USRP device. Through extensive experiments and analysis, we investigate the performance of different DoS attack strategies on the LQG control system over an inverted pendulum.
