The current efforts to digitize production processes in the industrial environment are associated with several challenges. While there is already a wide range of standards for mapping components and products, there is still a lack of solutions for communicating concrete product requirements and given capabilities of a plant or production hall. Previous approaches, which rely on standardized feature catalogs or rigidly defined semiotics, do not offer a satisfactory solution. More desirable is an intervention-free data exchange and a negotiation process that mediates between product requirements and setup conditions. To this end, this paper proposes an architecture of a marketplace whose components compare the capabilities of an industrial system with the product requirements and evaluate them in terms of their suitability to meet the desired requirements. An approach for the rapid recognition of equality in chemical compounds using GCN is examined in detail and transferred to an industrial context.

In respiratory control design there is a demand for technologies that integrate control systems with equipment efficiently. This research presents the model of a respiratory control to improve the levels of oxidation mainly due to quality of the air or for atmospheres with deficiencies of oxygen. In general, there is a complexity to obtain the mathematical models of a physiological breathing system associated to the concentration of the oxygen in the brain and in the body tissues. However, the model is designed by taking data into experimental tests for the plant or equipment modelling. In this research the control was developed in an Open-source electronic prototyping platform system. The control has two inputs and an output. In the methodology we obtain the transfer function of the plant controller. For the analysis of the closed loop control a system high-level model description was developed. Through these tools the controller selection and the stability analysis were made for a better performance. With the application of these methodologies the percentage overshoot and the settling time of the system were optimized. Finally, with a single-input, single-output (SISO) tool for controllers in feedback systems, the frequency responses of the close-loop system were analysed using the Nichols criteria. The present results are significant in at least one major respect that performance of the artificial respiration equipment was improved using these combined technologies.

Wafer transport by Automated Material Handling Systems is essential in modern semiconductor front-end factories to efficiently supply the manufacturing tools. Most common are ceiling mounted Overhead Hoist Transport Systems that allow high throughput and fast delivery times. These systems are increasingly supplemented by various types of Automated Guided Vehicle Systems that enable high flexibility. This development requires new approaches for transport system dispatching.We denote such Automated Material Handling Systems that combine several types of transport systems as heterogeneous. Here, vehicles with different characteristics can execute either a complete or a part of a transport order. Until now, this task allocation process for the vehicles is executed based on predefined rules. A dynamic exchange between the transport systems based on the current system state is not yet considered.This paper presents a formalization of the related planning problem by a mathematical model for transport system scheduling. The approach is not suitable for real-time decision making. However, on the one hand, it may help to identify and evaluate the solution quality of heuristic approaches. On the other hand, it allows the evaluation of the effect of transfers.

Due to various applications of variable frequency drives in industry, design procedure and control methods of these converters have attracted many researchers from both industry and academia. In this paper, a high power density AC-DC-AC converter design is presented alongside finite control set model predictive control method. Using model predictive control for the LC filter at the load side enables load voltage control which is an important issue in variable frequency drive applications. Also, input, output, and DC link filters’ design methods are presented and the results are compared to the designed filters in the literature. The comparison shows significant filter size decrease by using presented approach. Applying the proposed control method to the AC-DC-AC converter brings benefits such as simple implementation, robustness to the load changes, and fast dynamic response compared to conventional control methods. Finally, to demonstrate the effectiveness of the proposed design and control method, the designed variable frequency drive has been simulated and the results are presented.

Icon is an important element in human-computer interaction, and icon style is the most intuitive visual expression of icon design. Aiming at the problem of material classification in the icon style design process, this paper proposes an icon style recognition method based on deep learning. This paper first established the icon style dataset, and then used Visual Geometry Group Network (VGGNet), AlexNet and self-built neural network for training. The results show that the accuracy of the trained icon style recognition model is up to 100%. In addition, convolved features were visualized for explaining the recognition progress. This method can help designers quickly collect and filter a large number of icons of the same type, sequentially improving and accelerating the icon design process.

This paper is dealing with designing an advanced Direct Power Control (DPC) technique for a grid-connected nine-level Packed E-Cell (PEC9) inverter through Finite Control Set Model Predictive Control (FCSMPC) and Single-phase Direct-Quadrature (s-d-q) frame. Generating a nine-level voltage waveform using minimum active and passive components count makes PEC9 a cost-effective compact multilevel converter in single-phase applications. FSMPC symmetrically stabilizes the nine-level voltage waveform and accurately synchronizes the inverter current with the grid voltage by applying direct control to the switching operation of PEC9 inverter. The phase and the amplitude of the reference current in the proposed DPC are adjusted regarding the desired level of active and reactive power through s-d-q frame. In order to address the FCSMPC weighting factors tuning difficulty, some new adaptive functions using the error value of the capacitors voltages and the inverter current are also proposed. The experiments and simulations approve that PEC9 accurately generates the desired amounts of active and reactive power with standard level of THD and dc voltage ripple.

The addition of energy storage systems into the grid will allow to mitigate the effects of imbalances caused by the uncertainties of renewable energy sources. Energy storage facilities would give the grid more reliability and efficiency. One of the applications of these facilities is energy arbitrage, which is the trade of energy with the grid using price variability through the day to obtain a benefit. To impulse the investments on energy storage systems connected to the grid, they must be economically viable. The arbitrage operation can be optimized to ensure that viability. The optimization can improve the device’s profitability by controlling its degradation. This degradation management can be done in different perspectives attending to economical considerations which may change the way that profitability is viewed. In this paper, the mitigation of this deterioration process is done with two approaches by whether considering it as an operational or as an opportunity cost. Both approaches are compared, with simulation results of a Li-ion Battery Energy Storage System (BESS) performing arbitrage on the Spanish day-ahead electricity market. The main contribution of this work is the opportunity cost concept, which uses a more realistic calculation of degradation impact on arbitrage schedule.

In conventional EV powertrains the main energy storage system is based on battery banks. Potential higher current stress on battery during transient operation can considerably reduce its expected lifetime, while battery size is overrated to respond under heavy transient demands. The regenerative braking capability is also getting limited due to its charging dynamic constraints. Hybrid Energy Storage Systems (HESS) based on batteries and supercapacitors (SC) have the potential to solve this issue. However, SCs size and weight can deteriorate the power density of the solution. In this paper, a Partial Power Configuration (PPC) based on Dual-Active-Bridge (DAB) is proposed as a power interface to increase the power density of an HESS-based EV powertrain. A comprehensive efficiency analysis is provided, while transient dynamic results are provided to validate the proposed power configuration.

Energy modeling frequently relies on time series data, whether observed or forecasted. This is particularly the case, for example, in capacity planning models that use hourly production and load data forecasted to occur over the coming several decades. This paper addresses the attendant problem of performing sensitivity, robustness, and other post-solution analyses using time series data. We propose an efficient and relatively simple method, which we call the symmetric block resampling method, a non-parametric bootstrapping approach, for generating arbitrary numbers of time series from a single observed or forecast series. The paper presents and assesses the method. We find that the generated series are both visually and by statistical summary measures close to the original observational data. In consequence these series are credibly taken as stochastic instances from a common distribution, that of the original series of observations. We find as well that the generated series induce variability in properties of the series that are important for energy modeling, in particular periods of under-and over-production, and periods of increased ramping rates. In consequence, series produced in this way are apt for use in robustness, sensitivity, and in general post-solution analysis of energy planning models. These validity factors auger well for applications beyond energy modeling.

Introducing the excellent advantages of using wide bandgap semiconductors such as gallium nitride (GaN) in the construction of the power devices has set a starting point for a new era in the history of power electronics. Replacing the silicon-based with GaN-based power devices promises a number of benefits. Higher power densities, switching speeds and temperature stabilities with lower on-state resistance, reduced conduction and switching losses and a reduction in the die size are some of the performance improvements that the GaN transistors offer. To show both the advantages and challenges regarding this new technology, the methodology for an eligible comparison between Si-based and GaN-based transistors has been explained. Experimental comparison has been performed between a 100 V commercially available enhancement mode GaN FET and two silicon-based MOSFETs, and the results are discussed in detail.
