Short review on various applications of fuzzy logic-based expert systems in the field of solar energy

In this study, solar thermal desalination methods were developed to enhance the day to day efficiency of solar distillers by improving their portability and water purification properties. The performance of solar stills is highly contingent on environmental factors, making it essential to address these variables. To achieve this, a double-slope single basin solar distiller (DSBD) was upgraded by incorporating a partially coated absorber plate with ZnO/PVC/Bioactive nanocomposite (ZPBN), which was subsequently examined for its impact on drinking water production from multiple perspectives, including energy, exergy, environmental, and economic considerations. The ZPBN material was synthesized using the solvent casting technique, and its properties were comprehensively characterized through various analytical methods. X-ray diffraction (XRD) analysis revealed a regular crystalline lattice structure amidst an amorphous background, and scanning electron microscopy (SEM) images confirmed its surface performance. The presence of ZnO nanoparticles within the PVC and bioactive matrix imparted enhanced thermal characteristics to the DSBD, including higher temperatures, specific heats, and thermal stability compared to the ZPBN. The study demonstrated that the introduction of ZPBN significantly increased drinking water yield by up to 126% due to its enhanced absorption of solar energy. Furthermore, the energy efficiency of the DSBD improved by 0.44%, while its exergy efficiency decreased by 0.25% when compared to a conventional double slope single basin solar distiller (CDSBD) under the tropical climate conditions of Vijayawada, India. In terms of energy matrices, the ZPBN-coated basin area exhibited minimum and maximum energy payback times of 6.55 years and 0.15 years, respectively. Over its lifetime, the DSBD was found to reduce carbon dioxide emissions by 2.97 tonnes and offered the lowest cost per litre, amounting to $0.0360. The incorporation of ZPBN on the absorber plate within the DSBD resulted in excellent environmental and energy economies, with values of 4.640 kWh/$ and $83.210, respectively.

In this study, the effect of employing ZnO/Acalypha Indica leaf extract (ZAE) on the energy absorption of a coated portable solar cooker has been examined using an experimental setup. A prototypical model has been developed to corroborate in associating an investigative outcome per constituents of the experiments. The studied heat transfer process in ZAE is stable for harsh conditions. The design analysis and an estimation of the system performance were done given various parameters including the pressure of the vacuum envelope, bar plate coating digestion, emissivity, and solar rays. The fabricated solar was tested with and without ZAE to investigate the impact of this coating material on the solar cooker’s thermal performance. To observe the performance of the new design, two figures of merit (F1 and F2) have been introduced. The factual food cooking assessments were for a family of four people, which operated in ZAE coating (0.8, 1.0, 1.2 μm) of the solar cooker. The values of F1 and F2 for the proposed cooker were obtained as 0.1520 and 0.4235, respectively, which is intact with the BIS values. The results revealed that employing ZAE instead of a thermal NHC-PV solar cooker reduced the time required to boil 2 L of water for about 47 min. The overall thermal energy productivity of the solar cooker with electrical backup was obtained as 42.65%, indicating that the ZAE coating can improve the thermal efficiency by 10.35%.

An experimental analysis of a multi — sponge liner basins solar still is a device that produces clean, drinkable water from the Saline water by using the energy of the sun. In this a Double Slope — multi — basin Solar still has been performed on clear sunny day on summer and winter seasons at Vel Tech Multitech Dr. Rangarajan Dr. Sakunthala Engineering College, Avadi, at Chennai in Tamil Nadu India March 2016 to April 2017. The experimental analyses of the system have been shown that the first, second and third basin contributes 36.21%, 34.04 % and 29.05% of the total distillate yield respectively. He experimental analysis of Tribasin solar still have been made for one of the typical days calculation improve with other solar still.

In this work has been made to predict the effect of several parameters on the productivity to a system by expending fuzzy set technique. A solar cooker has been developed low cost and critically high efficiency produce in Vel Tech Multitech Engineering College at Chennai, Tamilnadu, India. Dissects in thermal performance of cooking system have been produced heat transfer follow in fuzzy logic techniques (Low, Medium, and High). The thermal effect of factor should be developed in fuzzy logic for the system. They should have groups of heat transfer produced in fuzzy logic controller for solar cooker system which had been implemented of system performance discussed. It is to study have induced to give the shortly time for the enhancement of the box solar cooker production.

High Performance of Solar Cooker by Heat Transfer Mode Condition System Using Fuzzy Logic Controller Applications

Ongoing research improvements in dc-dc converters have offered path way to high gain voltage of quadratic boost converter to control PMSM. Three phase inverter finds a way between semi converter and PMSM. This work demonstrates that, Semi-Converter fed Quadratic Boostconverter based on a permanent-magnet synchronous-motor drive for e-car is simulated with two different current control strategies.Further,this work presents the strategy, investigation & developed model of Semi-converter based Quadratic boost converter three phase inverter fed permanent magnetic synchronous motor (PMSM) with PIC-HC (Proportional integral controller-hysteresis controller) & PRC-PRC (Proportional Resonant controller - Proportional Resonant controller). The consequences are related in terms of settling time & steady state error. The consequences show the loftier presentation of HC controlled Semiconductor based Quadratic boost converter-three phase inverter (SC-QBC-TPI) fed permanent magnetic synchronous motor with improved response. 16F84-PIC based SC-QBC-TPI fed PMSM is tested and experimental results are presented.
