Abstract:
Four-leg voltage source inverter is an evolution of the three-leg inverter, and was ought about by the need to handle the non-linear and unbalanced loads. In this work Matlab/ Simulink model is presented using space vector modulation technique. Simulation results for worst conditions of unbalanced linear and non-linear loads are obtained. Observation for the continuity of the fundamental inverter output voltages vector in stationary coordinate is detected for better performance. Matlab programs are executed in block functions to perform switching vector selection and space vector switching.

Abstract:
A new control strategy that combines the resonant controller and the repetitive-controller based on the disturbance-observer (RSCDO) for off grid four-leg voltage source inverter (VSI) has been presented in this paper. The aim of the new controller is to regulate the inverter output voltage, reducing as much as possible the voltage total harmonic distortion (THDv) in every load condition. The resonant controller allows to adjust the voltage at the fundamental harmonic, while the repetitive observer is able to compensate the voltage distortions due to inverter nonlinearity. The proposed strategy has been at first validated by means of simulation results performed in MATLAB/Simulink environment. Then, the new control strategy has been implemented in field-programmable gate array (FPGA) using LabView environmental and experimental results are performed on the 40 kVA three-phase 4-leg VSI prototype.

Abstract:
The first power systems were DG systems designed to meet the needs of local areas.Full load DG applications showed greater benefits in terms of power and performance as well as reducing transmission losses. GDs are very suitable for a specific location and for specific applications because they require a short construction time and require little investment. It is defined on the basis of the size of the plant, which can vary from a few KW to MW (10-50 MW). GD options can be classified as renewable or non-renewable sources from fuel sources. This study deals with a newly-conceived voltage control method for three-phase four-leg voltage source inverters (VSIs) which are being required in autonomous power generating units devoted to supply both three-phase and single-phase electrical loads

<span lang="EN-US">This paper presents a new control strategy based on the combination between the resonant controller and the disturbance-observer (RSCDO) for stand-alone four-leg Voltage Source Inverter (VSI). The aim of the new controller is to regulate the inverter output voltage, reducing as much as possible the voltage Total Harmonic Distortion (THDv) in every load condition. The resonant controller allows to adjust the output voltage fundamental harmonic, whereas the disturbance observer is designed for compensating output voltage harmonics when non-linear loads have to be fed. The proposed control strategy has been tested using a 40 kVA three-phase 4-leg VSI and a dedicated control board, which uses the National Instruments System-on-Module sbRIO-9651. Experimental results demonstrate good behavior of the RSCDO controller to reject the disturbance in the output voltage, as well as a good dynamic response.</span>

Abstract:
This article presents a novel application of four leg inverter with conventional Sinusoidal Pulse Width Modulation (SPWM) Scheme to Unified Power Quality Conditioner (UPQC). The Power Quality problem became burning issues since the starting of high voltage AC transmission system. Hence, in this article it has been discussed to mitigate the PQ issues in high voltage AC systems through a three phase Unified Power Quality Conditioner (UPQC) under various conditions, such as harmonic mitigation scheme, non linear loads, sag and swell conditions as well. Also, it proposes to control harmoincs with various artificial intelligent techniques. Thus application of these control technique such as Artifical Neural Networks, Fuzzy Logic makes the system performance in par with the standards and also compared with existing system. The simulation results based on MATLAB/SIMULINK<sup>TM </sup>are discussed in detail to support the concept developed in the paper.

Abstract:
Energy-feed power electronic loads can precisely control the phase and magnitude of the power supply output current, achieving the emulation of loads. Moreover, they can feed energy back to the grid for energy regeneration, demonstrating significant research value. This article proposes an energy-fed power electronic load topology and control method that can realize the static and dynamic simulation of linear and non-linear loads and take into account the simulation needs of single-phase, three-phase three-wire, and three-phase four-wire loads. The main circuit uses a two-stage back-to-back AC/DC/AC structure: the front side is a three-phase four-wire split capacitor PWM rectifier bridge, which is used to simulate loads under various operating conditions; the back side is a three-phase three-wire PWM inverter bridge, which realizes the energy feeding back to the grid and reduces the waste of energy; and the intermediate side uses a split capacitor to equalize the voltage and achieve voltage stabilization. The topology is analyzed under the simulation demands of three-phase balanced, three-phase unbalanced, single-phase and non-linear loads. Finally, a MATLAB(R2022a)/Simulink simulation platform is built for a power electronic load with a rated capacity of 200 kVA. The simulation results verify the effectiveness, feasibility, and advancement of the power electronic load proposed in this article.

Abstract:
The low harmonic distortion and reduced switching losses are the advantages of using the multilevel inverter. For this purpose, the three-level inverter is used in this paper as a three-phase four-leg shunt active power filter (SAPF). The SAPF is used to eliminate the harmonic current to compensate the reactive power current, and to balance the load currents under an unbalanced non-linear load. A fuzzy logic controller and self-tuning filters (STF) are used to control the active power filter (APF) and generate the reference current. To demonstrate the validity of the proposed control strategy, we compared it with a conventional p − q theory, under distortion voltage conditions and unbalanced non-linear load. The Matlab-Simulink toolbox is used to implement the algorithm of Fuzzy logic control. The performance of the SAPF controller is found very effective and adequate as compared with the p − q theory.

Abstract:
<p>This paper proposes a reduced switch Open-Delta (OD-VSC) voltage controller for an standalone asynchronous generator (SAG), also known as the self-excited induction generator (SEIG),used in constant power applications such as pico hydro uncontrolled turbine driven isolated induction generator (IAG) for feeding three-phase loads. The proposed reduced switch voltage controller is used to regulate and control the generator terminal voltage as it is subjected to voltage drops, dips or flickers when the isolated power system is subjected to various critical loads. Generally this purpose is carried out by a STATCOM comprising of a three-leg six-switch inverter structure. Here, in this work the DSTATCOM is realized using a three-leg four-switch insulated gate bipolar transistor (IGBT)-based current controlled voltage-sourced converter (CC-VSC) and a self-supporting dc bus containing two split capacitors. The proposed generating system along with the controller is modeled and simulated in MATLAB along with Simulink and power system blockset (PSB) toolboxes. The system is simulated and the capability of the isolated generating system along with the reduced switch based voltage controller is presented here where the generator feeds linear and non-linear loads are investigated.</p>

Abstract:
Four-leg active power filter is considered one of the greatest vital active filters that are frequently used in industrial applications, especially those that need to be controlled in each individual phase. Also, to control the neutral current that created because of a lot of unbalanced and non-linear loads. In this paper, the used active filter was controlled by a proposed control method which can achieve simplicity and intelligence at the same time. The novelty of this paper is using the proposed controller with Four-leg active power filter. This controller relies on instantaneous reactive power theory, which used to create the required currents that are injected into the network via the used active filter to remove the problems created by unbalanced and nonlinear loads. It is also maintained that the current source a pure sinusoidal wave. The system is implemented on MATLAB/Simulink. The simulation results proved the preference of the proposed controller than the conventional proportional-integration controller, where it reduced the percentage of total harmonic distortion for the current source.

Abstract:
Overhead cranes are used widely in various industrial fields. Crane transportation load must be transported for the work efficiency and safety to the destination without swinging. As a demand of highly precise and safety rises, automation is thought about as a method corresponding to lack of operator of mastery of skills. A transportation load of an overhead crane swings by a traveling acceleration change while doing up-and-down motion of a rope length change. It is necessary to measure this three-dimensional motion for swing suppression control. When it is installed in an overhead crane, a measurement sensor becomes complicated. In this paper, the trial stereovision device is manufactured which is a non-contact sensor, not an installation sensor and tried to control the overhead crane by vision feedback. The vision sensor is a stereovision device of four degree of freedom for tracking and gazing with two CCD cameras. A position measurement of a transportation load and an experiment of tracking control were done. The three-dimensional position of the transportation load is provided with CCD image data of two cameras, the focus distance, and four-vision device drive angles and is used for crane control. The vision device drive target angles that a point of intersection of two camera optical axes seems to always accord with the transportation load center is obtained using inverse kinematics. With these target angles, the control of tracking and gazing about the transportation load can be done. On the other hand, in an overhead crane model, using measured three-dimensional coordinate values, positioning and vibration suppression control of the transportation load was done. The overhead crane model consists of a trolley running on two perpendicular slide guide rails and a hoisting device of the transportation load. The overhead crane model has five degree of freedom, and they are x, y direction displacements of a trolley, a rope length, a swing angle, a swing direction angle. The variable rope length, the swing angle and the swing direction angle are calculated using the load position measured by the vision sensor. Variable digital gains of the trolley in consideration of the rope length change were pursued by this information, and overhead crane control was done. The experiment result of overhead crane control by vision feedback showed that the used control system was effective.
