Transformerless inverters are widely used in grid-tied photovoltaic (PV) generation systems, due to the benefits of achieving high efficiency and low cost. The transformerless photovoltaic inverter may generate a leakage current between the inverter and the grid, through a parasitic capacitance. This leakage current will cause a low efficiency a distortion of the output and should the staff be in danger. Several transformerless inverter topologies have been proposed to reduce this leakage current. This paper proposes a different topology to reduce the leakage current problem, which consists of the stage integration of a full bridge inverter and a DC/DC boost converter. One output terminal of the inverter is connected directly to the ground; the inverter is controlled using the sliding mode control.

Various driving support systems to avoid traffic accident have developed and have been put in the real world. On the other hand, only a few collision avoidance systems with the steering wheel have been put in the real world. In addition, most of these systems target avoiding other vehicle. But the number of traffic accidents concerned with a bicycle is next to it of a vehicle. So driving support system for collision avoidance of the bicycle is necessary. In this paper, steer-by-wire is introduced into the steering wheel of the vehicle and the driving support system which realizes the most suitable steerage to avoid collision with the bicycle by considering position, velocity, and inclination of running bicycle is proposed. First, the modeling of the driving support system is introduced. Second, the control system is designed which is composed of impedance control and model predictive control. Third, the driving simulation is conducted to verify the effect of the proposed method. Finally, conclusion and the future works are described.

In this study, we describe a novel method of fabricating shape-controlled calcium alginate gel microcapsules. Alginate-poly-L-lysine (PLL) hydrogel microcapsules with predefined shapes were constructed based on electrodeposition method. Firstly, electrolysis of water in alginate solutions with calcium carbonate particles induced alginate gelation on micro-patterned electrode to form 2D gel structures. Then, these structures will be detached from the electrode surface and treated with the alginate-PLL microcapsules system. By passive control based on the micro-pattern geometric confinement and electrodeposition parameters, we succeeded in producing calcium alginate-PLL microcapsules with diverse shapes (such as sphere rod and cubic). The shape and size of the calcium alginate microcapsules could be tuned by adjusting the geometric design of micro-pattern on electrode and the apply voltage of electrodepostion. The preparation conditions of size- and shape-controlled calcium alginate-PLL microcapsules and influence factors were studied. This proposed method can lead to more accurate and creative studies of fabricating biocompatibility scaffold for tissue engineering.

In brushless dc machines the current commutation between phases is triggered based on information of the permanent-magnet flux position. In most BLDC drives, either sensors are used to detect this flux position or a self-sensing algorithm is applied to estimate the flux position instead. Over the last decades, different techniques have been developed to detect the current commutation instants from the speed-induced back-emf signal. Several of these methods when used in open-loop speed control show speed variations at an increasing acceleration. These speed variations are often reduced by closing the speed control loop that adapts the current amplitude to generate a torque for stable speed operation. This paper studies the open-loop behaviour of back-emf based self-sensing BLDC drives and gives a criterium for which the average speed acceleration over a time period is zero. The criterium depends on the machine inertia, speed and torque and indicates the robustness of the self-sensing method against speed variations. Fulfilling the criterium reduces the burden on the speed-controller to guarantee stable speed operation. Even in the ideal case where noise on the measured back-emf is absent and small voltages can be measured accurately, the application of a self-sensing method can be hampered due to a lack of robustness against speed variations if not well-designed.

Integration of renewable energy sources (RES) into the ac grid is growing very rapidly to meet the high and reliable load demand. The penetration of this growing microgrid structures within the distribution network are leading to several challenging power quality issues. It is mandatory to maintain the voltage and frequency within the prescribed limits at the local bus under any condition of the renewable sources and load. It is a known fact that the behaviour of RES, loads are unpredictable and the need for energy storage system (ESS) becomes extremely important. The sharing of power among grid, RES and storage plays a very vital role for the stable operation of grid integrated microgrid system. Also, the energy storage devices (ESD) need to be operated within its safe limits. Hence a simple control algorithm for power management is being formulated to generate references for RES, ESS interfaced power electronic converters and grid connected converter to mitigate the power imbalance within the dc grid and support sudden frequency variations of the ac grid. Further this method also improves the power quality condition of the ac system. The proposed algorithm is tested and validated using MATLAB based Simulink environment.

Based on magnetic induction, wireless power transfer have been proved to be promising in many applications, especially in EV charging systems. The coupling performance of loosely coupled transformers determines the overall feasibility of the whole systems. Considering volume, cost and coupling properties, a solenoid magnetic structure of 400mm*600mm with a 200mm air gap is utilized to transfer power in this study. By FEM simulation tools, the distance of wires and the coverage length are discussed to find the best coupling design. In addition, the position of the magnetic stripe cores is analyzed when taking account of the system cost. Moreover, additional shielding devices, which are made of aluminum, are designed to eliminate the back leakage magnetic flux. In order to improve the coupling performance, flux guiding ferrites are also added into the shielding devices to guide more leakage to flow to the secondary windings. Simulation results indicate the proposed design can increase the coupling coefficient k dramatically. Also, experimental results show great agreement with the simulation results.

With the rapid development in internet and video coding technology, applications such as telesurgery and remote operations are becoming more and more popular. In such applications, any delay will significantly lower the performance and may sometimes lead to catastrophic results. As a result, low-delay video streaming is demanded in such applications. Previous works have explored and established several live streaming systems based on fixed size block partitioning. Considering the effectiveness of identifying and extracting regions with similar image characteristics using variable sized block partitioning, this paper attempts to propose a live streaming system with variable sized block partitioning utilizing the quad-tree structure for low-delay live video streaming under limited bandwidth.

A communication system allows getting the measurements and to change the modulation and control strategies from PC. In addition, the developed prototype has made possible the fast development of some application examples such as pot detection and power control.

Modern variable-speed induction machine drives are widely used in traction applications such as hybrid or fully-electric road vehicles despite their lower efficiency compared to interior permanent magnet synchronous machine drives. The machine terminals are fed by a voltage source inverter that implements a field-oriented current control. The rotor flux and torque producing current component can be controlled independently and should be optimized to achieve maximum efficiency in all operating points. This work presents an approach to calculate the loss distribution in the machine and the inverter explicitly. Special focus is set on the consideration of magnetic saturation with the help of a 2D magnetostatic finite-element calculation. The solutions of the optimization problems are stored in look-up-tables. The control uses them to modify the flux level for minimal total losses over the whole speed range respecting the current and voltage limits. The control structure can be implemented easily and gives optimal results for machine parameters disregarding temperature effects. To adapt to heating of the machine it is then enhanced by a new discrete search algorithm based on a simplex state machine. Simulation results for both methods are provided and compared to standard operation. The combination of model-based loss minimization and search control seems most promising to reach true loss minimal operation.

In this paper, we present a geometrical scattering model for a typical class of industrial indoor environments. The proposed industrial reference model takes into account scattering components arising from metallic structures and the surrounding walls of the investigated environment. Starting from the geometrical scattering model, we derive the analytical expressions of the probability density function (PDF) of the angle of arrival (AoA), PDF of the time of arrival (ToA), and the autocorrelation function (ACF) in the frequency domain. The obtained results reveal a large difference between industrial channels and other home and office environments. The theoretical results of the reference model are validated by simulation results of a channel simulator designed by employing the sum-of-cisoids (SOC) principle. The proposed channel model is useful for the design and performance evaluation of wireless communication systems operating in industrial environments.
