The architecture of an Advanced Metering Infrastructure with Device Level Load Monitoring (AMI-DLLM) is proposed in this paper. The AMI-DLLM architecture is an upgrade from currently available Advanced Metering Infrastructure (AMI) that is enabled by large-scale smart meter rollouts under National Smart Metering Program (NSMP) across Australia. Potentials of such massive volume of demand side data...
The distribution domain of the smart grid incorporates advantages of the newest substation automation standards in order to enhance distribution network automation. State-of-the-art distribution automation solutions use the public Internet for exchanging data between substation and control center. This presents challenges for cybersecurity, particularly for critical data determining distribution network...
This paper proposes a novel method of killing birds and applying vaccines for suppressing the spread of avian influenza via a nonlinear switching control approach. The switching strategy is based on the population of the susceptible birds and the population of the susceptible humans. There are four switching cases. For the first three switching cases, the elimination control force and the quarantine...
The PI algorithm has proven to be a popular and widely used control method, due to its relative simplicity and robustness. Despite this, the linear nature of the algorithm means it doesn't provide optimal control to non-linear systems. This paper presents a novel method of improving the performance of the PI controller using an ANFIS network to provide gain scheduling. This control scheme is applied...
In this paper we introduce a digital holographic technique called optical scanning holography (OSH). In OSH, the object to be measured is raster scanned by a pre-generated time-varying interference pattern. In addition, a single-pixel detector instead of an arrayed detector is used to acquire the hologram data. By using heterodyne technique in conjunction with synchronous demodulation, a complex hologram...
The present paper presents an study on the harmonics introduced by thyristor-based soft-starters in the induction motor starting current. It is observed how the use of these starting elements leads to the amplification of the amplitudes of some specific harmonics. The application of continuous time-frequency decomposition tools enables to visualize the full transient evolutions of these harmonics...
We discuss and demonstrate our recent developments using self-interference incoherent digital holography to bridge the gap between indispensable incoherent imaging techniques and the advantages of three-dimensional holographic recording. We demonstrate the ability to record broadband sunlit photographic holograms, apply non-invasive three-dimensional tracking techniques, and the ease of adaptation...
Digital holography can serve as an effective tool for imaging three-dimensional scenes or objects, quickly and reliably. In this paper, recently developed methods of self-reference single channel digital holography are reviewed: Fresnel incoherent correlation holography (FINCH), Fourier incoherent single channel holography (FISCH), and the joined object reference digital interferometer (JORDI).
We propose a method to combine two phase-shifted holograms into a complex hologram. The reconstruction of the complex hologram will have no twin image noise but have a constant zeroth-order beam, which could be attenuated by subsequent optical filtering of the reconstructed image.
Ultrasonic Guided Wave (UGW) based NonDestructive Testing (NDT) systems are widely used in numerous branches of industry, where the structural integrity of components carries vital importance. In those systems, signal interpretations might become challenging due to multi-modal and dispersive response of the structure under examination. This results in degradation of the signals in terms of Signal-to-Noise...
The purpose of this research is to realize the novel palpation method called “organ palpation”. In conventional palpation method, the doctor knows the hardness of organ by his force sense. However, the organ palpation can get the quantitative hardness value by pushing the organ directly. In order to measure the hardness of organ directly, a remote actuator and an endoscope are utilized. In this paper,...
Limited availability of resources increases the importance of decentralized control through optimal networking of sensors and controllers in practical MIMO systems. Design of this network entails rigorous consideration of constraints in sensors, communication relays as well as controllers. Given that each of these elements has different capacity, a framework for optimal allocation of communication...
Cyber-physical systems (CPS) integrate computation with physical processes. For the last years, CPS have been in the focus of research and are getting adopted in multiple domains like health care, automotive and smart factories. The use of CPS promises dynamic adaption of systems to changing environmental and economic conditions through autonomous CPS decisions based on the physical process. In industrial...
A 12/14 bearingless switched reluctance motor (BLSRM) with hybrid stator poles has been proposed due to the outstanding decoupling characteristics between the torque and suspending force. However, the motor is a two-phase motor. The output torque of the motor has torque dead zone and high torque ripple. Hence, the motor cannot self-start at some rotor positions. To solve the self-starting problems...
With the technological development of robotics, a bilateral control based on acquiring and rendering tactile sensation, which is one of the human five senses, enables human to manipulate by using wireless network. In order to realize the applications of haptic transmission as well as audio and visual information, the research field of haptic data compression will be considered. However, information...
Industrial control systems are an important part of critical infrastructures and their uninterrupted operation is important for many aspects of society. In recent years these systems have come under more scrutiny, as reports about attacks on them have become more frequent. There is therefore a need to better secure them, and the first step to achieve this is to identify the threat landscape for such...
Approximation of unknown functions in multiple dimensions is an important topic in many areas of industrial engineering, such as nonlinear control. Currently, approaches such as neural networks or fuzzy systems are used to create highly nonlinear surfaces from data. Here we show the capabilities of a very simple classical numerical method such as cubic spline to compete with state of the art machine...
