Proportional-integral-derivative (PID) control schemes have been widely used in most industrial control systems. However, it is difficult to determine a suitable set of PID gains because most industrial systems have nonlinearity. On the other hands, the cerebellar model articulation controller (CMAC) classified as neural networks has been proposed, and design scheme of an intelligent PID controller...
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...
As Smart Manufacturing, Industrial Internet, Industrie 4.0, and Cyber-Physical Production System (CPPS) are becoming reality, the way process and manufacturing plants are operated has to change. Additionally, these developments - constituting the pervasive digitalisation of industry - have a profound effect on the way human workers and machines interact. This paper contrasts the current state of the...
The Virtual eXperiences Lab at RMIT is a “21st century lab scope,” an enabling platform for research and prototyping in industrial automation, focusing on software engineering, next generation human-machine interaction experiences, user interfaces, and training. VxLab combines high resolution visualization, industrial automation facilities and cloud-based simulation servers in a dedicated private...
In today's marketplace machine producers are shipping their systems all around the world. Maintenance costs are becoming ever greater due to travel costs for sending service personnel to wherever the machines are installed to solve a particular problem. In the majority of cases, a technician solves the problem quickly, so that the travel overhead becomes a large part of the repair cost. This makes...
In packaging industry, the duration of the carton folding plays a fundamental role in the production process; in particular in the erection process when each panel rotates around the die-pressed lines called creases. Their bending response can be very complex, depending on forming and environment conditions. The crease mechanical properties, such as geometrical parameters, temperature, moisture and...
Using micro-sensors in industrial applications is of great interest due to their small size, low-cost and little power consumption. However, the harsh environmental conditions encountered in an industrial environment have so far hindered the widespread use of, for example, MEMS-based sensors. Such sensors are particularly suited for mobile condition monitoring of industrial machinery as short time...
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”,...
This paper deals with modeling the temperature of a room in a smart building. Two different approaches are analyzed and compared. The first one is based on a black-box identification procedure, which yields a fairly simple dynamical system that is suitable for real-time control. The second approach is based on first principles, it requires a complex and time consuming calibration procedure but it...
Welding joints for offshore oil rigs present a complicated geometry and require multiple passes. This paper introduces a complete collision-free offline path planning approach for such joints. Collision detection is performed using A* search on a three dimensional grid, where triangular mesh representations of the welding joint and its fixture form the objects. A workflow is proposed for the complete...
Due to the material changes of components from metal to plastic or composite materials, the structural health monitoring finds more and more interest in the industrial fields. The reason is that these materials are more vulnerable to damage or impacts which cannot be optically detected. In this contribution we present a method to analyze the structure of plastic components with piezo-electrical sensors...
With the growing ubiquity of Internet of Things (IoT), myriads of smart devices connect and share important information over the internet. In order to provide connectivity and interoperability of all the existing heterogeneous wireless devices, a full communication stack is proposed by the IoT Architecture Reference Model (IoT-ARM). From the sensor to the cloud, the proposed stack can be implemented...
This paper deals with a way to probabilistically guarantee reliable packet delivery in WirelessHART based networks suitable for industrial control systems. We propose a new scheduling scheme, called Iterative Probabilistic Scheduling with Adaptive Relaying (IPS-AR), which consists of a static part (IPS) and a dynamic part (AR). IPS takes into account the channel characteristics and exploits relaying...
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...
IIoT (Industrial Internet of Things) cloud applications require reliable, fault-tolerant networks, supporting real-time guarantees and allowing interaction with other applications already existing in the datacenter. The Software Defined Networks (SDN) paradigm is especially suited for the management of the network cloud because of its fine grained admission control and the management flexibility provided...
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.
Distributed embedded systems (DESs) that operate in dynamic environments require emerging flexibility and adaptivity communication requirements. When those DESs are deployed for critical applications, they must also employ appropriate fault-tolerance (FT) mechanisms to attain a high level of reliability. The FTT-Ethernet communication protocol supports the flexibility needed in dynamic environments,...
Distributed embedded systems (DES) have traditionally been designed assuming that the requirements they need to satisfy are known in advance. If this is not the case, and a DES should operate autonomously without interruption, it needs to be adaptive. For this, flexible approaches are necessary and this applies in particular to the network of the DES. However, if the probability of faults occurring...
In this paper, a novel spectrum handoff scheme for cognitive ultra-wide band industrial networks (CUWBINs) is proposed, where secondary users (SUs) can access the licensed channels despite the present of primary users' signals. To maintain continuous connectivity between the cognitive users, licensed channels can be opportunistically used by an SU as long as its transmission does not interfere with...
PID control schemes have been widely used in most process industries. Since the control performance strongly depends on PID parameters, it is important to suitably choose a set of these parameters. Especially, it is difficult to determine these parameters in the case where the time-delay is unknown and/or large. On the other hand, it is well-known that the generalized predictive control(GPC) design...
