This article supplies a proposed approach Neuro Fuzzy Controller (NFC)-Adaptive Backstepping Controller (ABC)-Space Vector Modulation (SVM) for a five-level NPC inverter-Double Stator Interior Permanent Magnet Synchronous Motor (DSIPMSM). This paper's primary objective is to enhance DSIPMSM's performance by the use of strong control using the proposed approach. Given its benefits - including high torque density, high efficiency, high power density, and minimal maintenance - DSIPMSM, have recently been the focus of much research. Using the input-output linearization approach and Lyapunov stability theory, asymptotically stable trajectory-following dynamics are demonstrated using nonlinear adaptive backstepping control. The use of fuzzy logic and intelligence-based controllers are increasingly being used to enhance traditional control's performance and output. In addition, the fuzzy logic controller has a lot of flaws that are presently being fixed by the extremely effective NFC tool. The proposed method's worth was demonstrated by the simulation results in terms of durability, effective tracking dynamics, precision, and good disturbance rejection with little ripple. © 2024 IEEE.

This paper presents a general study of the instruments and control strategies involved in the design of a hybrid microgrid (HMG), where multi-source power production unites are spread within its local confines. The primary goal of this endeavor is to observe, analyze and document the feasibility and performance of hybrid topologies, where a region of stability is adopted for the analysis of system's response to a step load. The characteristics of the employed devices, namely;current source converters (CSC) on the DC side and paralleled voltage source inverters (VSI) are viewed from a power generation standpoint. For the DC part of the HMG, coordinated power sharing is achieved by super imposing the currents of the sources to possible values that correspond to a desired point on each source's power production chart. On the AC side, a droop controller is implemented to coordinate the energy production of the different source supplying the AC bus. © 2024 IEEE.

In this study, operational strategies are investigated for an air-based photovoltaic-thermal (PV-T) system integrated with a domestic air-to-water heat pump. The PV-T system is used to simultaneously generate electricity and heat ambient air, which serves as the heat source for the heat pump. By utilising a variable-speed fan to regulate airflow, the PV-T system outlet temperature is adjusted, and the focus is on how different outlet temperatures impact the PVT system electrical and thermal efficiency, heat pump performance, and overall electricity requirements for heating. The performance of the integrated system is assessed for a case study of a household application in north Italy. The optimal PV-T outlet temperature is found to be between 30 - 35 °C, resulting in only 5% less electricity production than an equivalent PV system with equal nominal electricity capacity, while reducing overall electricity required for heating by over 15% compared to PV-integrated heat pumps. © 2024 IEEE.

Short-circuiting flow is an important secondary flow in gas cyclones, which has a negative impact on the separation performance. To improve the understanding of the short-circuiting flow and guide the optimization of gas cyclones, this paper presents a numerical study of a cyclone using computational fluid dynamics. Based on the steady flow field, three methods were adopted to investigate the formation mechanism and characteristics of the short-circuiting flow and particles. The temporal variation of the tracer species concentration distribution reveals that the formation mechanism of the short-circuiting flow is the squeeze between the airflows entering the annular space of the gas cyclone at different times. The short-circuiting flow region, distinguished through the spatial distribution of the moments of age, is characterized by a small mean age and a large coefficient of variation. The proportion of the short-circuiting particles increases with the increase of the inlet velocity only for small particles. But with the increase of particle size, the proportion of the short-circuiting particles decreases faster at higher inlet velocities, resulting in significant differences in collection efficiency curves.

Solar energy has advanced to rank among the top renewable energy sources in the world today due to a number of factors, including sustainability. Solar energy is a naturally replenishing renewable energy source that does not quickly run out of supply. We can depend on the sun as a source of energy for thousands of years without damaging the biosphere. Additionally, solar panels can produce a lot of electricity even in areas with little sun exposure. Monitoring and identifying problems with self-sustaining solar panels have become increasingly crucial with the rise in their utilization. In this regard, a cutting-edge strategy (Adaptive Neuro -Fuzzy Inference System) largely reliant on smart technologies and hybrid artificial intelligence is suggested to guarantee and boost energy efficiency and improve the dependability of existing solar panels in the Algerian desert. Temperature variations and variances in solar radiation intensity cause substantial climate fluctuations in this area. This suggested method makes use of real-world data gathered from the examined system to help increase electricity output and promptly address any problems that may occur, assuring a steady supply of energy to remote places. In fact, the intelligent diagnostic method has produced remarkably accurate results, enabling the timing of the studied photovoltaic panels' flaws and the early diagnosis of any system problems. As a result, these systems are more productive and maintenance downtime is decreased. © 2023 IEEE.
