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.

The IEC 61449 standard provides an outset for designing and deploying distributed control systems. Recently, a mapping from IEC 61499 to the RTFM-kernel API has been presented. This allows predictable real-time execution of IEC 61499 applications on light-weight single-core platforms. However, integrating the RTFM-kernel (bare-metal runtime) into potential deployments requires developing device drivers, protocol stacks, and the like. For this presentation, we apply the mapping from IEC 61499 to the RTFM-MoC task and resource model implemented by the RTFM-core language. The compilation from RTFM-core can be targeted to both, RTFM-kernel and the introduced runtime system RTFM-RT. In this paper, we detail the generic RTFM-RT runtime architecture, which allows RTFM-core programs to be executed on top of thread based environments. Furthermore, we discuss our implementation regarding scheduling specifics of Win32 threads (Windows) and Pthreads (Linux and Mac OS X). Using our RTFM-RT implementation for deployment, predictable IEC 61499 execution together with access to abovementioned operating system functions are achieved. For further developments, we discuss the needed scheduling options to achieve hard real-time and analysis required to eliminate deadlocks.
IEC 61449标准为设计和部署分布式控制系统提供了一个开端。最近，给出了从IEC 61499到rtfm内核API的映射。这允许在轻量级单核平台上可预测地实时执行IEC 61499应用程序。然而，将rtfm内核(裸机运行时)集成到潜在的部署中需要开发设备驱动程序、协议栈等。在本演示中，我们将IEC 61499中的映射应用于RTFM-MoC任务和资源模型，该模型由rtfm核心语言实现。从RTFM-core编译可以同时针对RTFM-kernel和引入的运行时系统RTFM-RT。在本文中，我们详细介绍了通用的RTFM-RT运行时体系结构，该体系结构允许在基于线程的环境之上执行rtfm核心程序。此外，我们还讨论了关于Win32线程(Windows)和Pthreads (Linux和Mac OS X)调度细节的实现。使用我们的RTFM-RT实现进行部署，实现了可预测的IEC 61499执行以及对上述操作系统功能的访问。对于进一步的开发，我们将讨论实现硬实时所需的调度选项和消除死锁所需的分析。

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.

In recent years, cloud computing, which provides users with network resources such as memory and computing power depending on the users' needs, has gained enormously in importance. Providers such as Amazon allow the users to access their cloud storage and computing resources by different interfaces. In this regard, guaranteeing compatibility is a severe issue as many different proprietary interfaces exist for accessing data in different clouds. The solution to this problem is the RESTful Cloud Data Management Interface (CDMI) standard, which has passed the ISO audit as first standard and is therefore evolving into the most common standard for accessing clouds. This paper investigates the combination of CDMI with a P2P-based storage and computing back-end in order to realize a self-organizing cloud for distributed data storage and processing called DuDE-Cloud. The basis is the self-organizing hash table (DHT)-based P2P storage and computing back-end called DuDE, which utilizes the DHT protocol Kad. DuDE is able to bundle existing storage and computing resources of different devices dynamically and has already proven its advantageous performance over centralized solutions. In a test scenario, resources of DuDE-Cloud were successfully accessed through CDMI using a GUI front-end thereby proving the proper functionality. As a result, a resilient high-performance distributed cloud solution is available that is compatible with other clouds.

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 affected equipment and dependencies between plant elements. We discuss the proposed application and present the architecture and implementation. Based on incoming events the framework selects, aggregates and displays information automatically for human processing possibly at distant control centres. For example an alarm in a manufacturing facility can trigger the display of relevant information on multiple devices such as workstations, tablets, or large control-room screens to supervisors and experts. Devices can be potentially in different locations and can comprise different visualization capabilities. The core of our framework uses semantic models and formal methods-based techniques to aggregate and process this information.

For safe human-robot interaction and co-existence, collision avoidance is a fundamental prerequisite. Therefore, in this contribution a Nonlinear Model Predictive Control approach for fixed-base and mobile manipulators is presented that allows for avoiding self-collisions and collisions with static and dynamic obstacles while performing tasks defined in the Cartesian space. The collision avoidance takes not only the end-effector but the complete robot consisting of both platform and manipulator into account and relies on a 3D obstacle representation obtained by fusing information from multiple depth sensors. The obstacle representation is applicable to all kinds of objects. It considers occlusions behind the obstacles and the robot to make a conservative assumption on the obstacle size. In order to achieve realtime reactions to obstacles, the obstacle information used in one control step is restricted to the most relevant obstacles determined by distance computation. The method is validated by means of simulation and by application to an omnidirectional mobile manipulator with 10 degrees of freedom.

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.

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.

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.
