The recent advancement of industry automation is underpinned by the continuous development of the industrial network. This exponential growth is driving the fourth generation industry revolution (FGIR). To meet the requirement of FGIR, there is an ongoing evolution of industrial network from Fieldbus to Ethernet that has emerged a new opportunity to integrate Software Defined Networking (SDN) technique...
This paper proposes a design pattern based on the service-oriented architecture for the design of flexible distributed automation control system for substation automation systems. The design pattern is intended to be applied to control systems based on the leading standards for software development of smart grid: IEC 61850 and IEC 61499. The proposed design pattern models system requirements as orchestrators...
This report shows that the architecture of Big Banks' Management Control Systems can be presented as a two or three-tier structure without separating the functional components to the front and back office. The report also examines the key legislative and regulatory documents that define the specific requirements for the Big Banks' Management Control Systems' Software. Functional components' classification...
This paper proposes a novel architecture for control systems of modular reconfigurable robots that combines centralized and decentralized approaches to achieve the best ration between efficiency, fault-tolerance and cost-efficiency.
Software Defined Networks split the data plane from the control plane. They can be used in wireless networks and will bring flexibility, less interference, simple management, less energy consumption and load balancing. They can also improve service quality, handover and mobility between different service providers. In previous methods, when link states were changed the controller deleted the stored...
Data assurance and resilience are crucial security issues in cloud-based IoT applications. With the widespread adoption of drones in IoT scenarios such as warfare, agriculture and delivery, effective solutions to protect data integrity and communications between drones and the control system have been in urgent demand to prevent potential vulnerabilities that may cause heavy losses. To secure drone...
Software-Defined Networking (SDN) is an innovational network architecture introduced a couple of years ago. It gives network administrators the ability to directly control the whole network by programming on a centralized controller, without manually configure each device. However, new security challenges come out with SDN development. One significant challenge is to design a secure firewall specifically...
Technological advancement of Industrial Control Systems (ICS) and control systems automation over the past decade has brought greater interconnections of the control components. Modern control communication systems such as ModbusTCP are based on open standards that leverage Ethernet to allow interoperability between solutions from different vendors. The enhanced exchange of information has, as a side...
In this paper a circuit-oriented approximate solution to an explicit nonlinear Model Predictive Control (NMPC) problem is proposed, based on piecewise-affine functions defined over simplicial domain partitions. The resulting controller is suitable for circuit implementation in programmable devices, such as microcontrollers or FPGA, enabling the application of NMPC to systems with low sampling times...
This paper presents a methodology to calculate the worst-case reliability of smart distribution system. Impact of communication infrastructure failure on the system reliability is investigated in both substation-centered and decentralized multi-agent restoration management. Different communication infrastructure is also examined to evaluate the impact in the reliability of the substation centered...
Software Defined Networks (SDNs) is the latest technique that has made the existing networks more efficient in terms of scalability, performance and economical. However, SDNs are more vulnerable to different attacks and vulnerabilities. SDNs security is a major concern for all the stakeholders. The SDNs have centralized controller that is resilient to many security threats but the security attack...
Software Defined Networking (SDN) is on strike around the world. Many scientists, researcher, IT and telecommunication professionals are focusing on it. SDN is the upcoming superb, centralized, cost-effective, programmable and agile future networking system. As the current computer networks are complicated and difficult to superintend we need SDN to make the network and telecommunication services...
International Standardization activities enabling future Smart Manufacturing have been actively considered in many standard organizations. In the current Industrial Automation systems, there are many published International Standards, such as Technical Committee No. 65 (TC65): “Industrial Process Measurement, Control and Automation” of the International Electrotechnical Commission (IEC) developed...
This paper focuses on a possible evolution of the control architectures suitable for Integrated Power Systems in modern all-electric ships. In control systems there is a major trend in using information and telecommunication technology as general real-time operating systems and standard communication protocols. This trend leads a standardization at software and communication protocol level that is...
In this paper, we propose a resilient network and control co-design architecture, Wireless-Simplex (W-Simplex), which can guarantee control performance by adaptively tuning the network and control parameters against wireless channel uncertainty in cyber-physical systems (CPS). To the best of our knowledge, there has been no study on resilient network and control co-design in response to the unreliable...
This paper presents an all-digital background blind calibration technique for the capacitor mismatch problem in SAR ADCs. It utilizes the redundancy offered using a sub-radix-2 DAC architecture to blindly estimate the mismatch and the assigned weight for each comparator decision. The weights are estimated by building partial histogram windows for the comparator decision vectors. To remove the dependency...
Teaching is one of the essential elements, which impact the learning process. An effective teaching happens only if the students can hear and grasp what is taught clearly. In a classroom, teachers' voice quality will greatly affect the students' comprehensibility and interest in learning. So teachers should make sure that every student in the classroom could hear the voice in clear, precise and audible...
In Software Defined Networks (SDN), the switches are statically assigned to controllers, which cause load imbalance among controllers. Among other problems, congestion, delay in SDN control messages, and controller overload are usually risen, especially in high traffic networks like data centers. In this work, we consider a distributed SDN controlling switches running OpenFlow protocol. We propose...
