In this paper, digital proportional-integral-derivative (PID)-type and fuzzy-type controllers are compared for application to the buck boost dc-dc converters. Comparison between two is made with regard design methodology, implementation issues, experimentally measured performance. Design of fuzzy based on heuristic knowledge converter behavior, tuning requires some expertise minimize unproductive trial error. The PID control frequency response converter. Implementation linear a signal...
This research investigates 3- and 5-year-olds' relative fairness in distributing small collections of even or odd numbers more less desirable candies, either with an adult experimenter between two dolls. The authors compare than 200 children from around the world, growing up seven highly contrasted cultural economic contexts, rich poor urban areas, to small-scale traditional rural communities. Across cultures, young tend optimize their own gain, not showing many signs self-sacrifice...
In this paper, a robust adaptive sliding-mode controller is designed for boost converter with an unknown resistive load and external input voltage. Adaptation laws are using state observers. The closed-loop system the shown to be asymptotically stable. Finally, robustness of voltage uncertainties variations tested experimentally.
Objective: Internet gaming disorder (IGD) has been investigated by many behavioral and neuroimaging studies, for it became one of the main behavior disorders among adolescents. However, few studies focused on relationship between alteration gray matter volume (GMV) cognitive control feature in IGD Methods: Twenty-eight participants with IAD twenty-eight healthy age gender matched controls participated study. Brain morphology adolescents was using an optimized voxel-based morphometry (VBM)...
The sensitivity of the analog-to-digital converter and inherent time delay in a digital controller can degrade steady-state performance DC-DC power converter. Analog PID controllers were designed for prototype buck boost converters then implemented on TI DSP. Three modifications to investigated improve their performance. dead zone, an averaging filter two sets gains. monitors output voltage error determine if modification should be employed calculate next duty cycle. Experimental results...
A constant voltage maximum power point (MPP) algorithm that automatically adjusts the reference to account for varying environmental conditions is presented. simple (and inexpensive) analog feedforward PWM controller developed continuously track MPP of a solar cell array as weather vary. The source configured such its open-circuit sampled without breaking entire from load case with other algorithms. MATLAB/Simulink simulations are presented demonstrate performance proposed algorithm....
Root locus techniques to design digital controllers for buck and boost converters are discussed in this paper. The small signal models of both first transformed into discrete-time using the matched pole-zero mapping method. Digital designed based on model root By selecting poles, zeros gain controllers, closed-loop poles placed at desired locations z-plane. then implemented a TI DSP. method is compared with frequency response Experimental results from converter indicate that obtained...
Abstract Glioblastoma (GBM) is among the most aggressive human cancers. Although oncolytic virus (OV) therapy has been proposed as a potential approach to treat GBM, it frequently fails because GBM cells are usually nonpermissive OV. Here, we describe dual-step drug screen for identifying chemical enhancers of OV in GBM. From high-throughput 1416 FDA-approved drugs, an inhibitor CDK4/6 was identified top enhancer, selectively increasing potency two strains, VSVΔ51 and Zika virus....
Implementation of digital PID controllers for DC-DC converters is discussed in this paper. The primary advantages control over analog are higher immunity to environmental changes such as temperature and aging components, increased flexibility by changing the software, more advanced techniques reduced number components. Analog PI were first designed using frequency response techniques, then converted into controllers. Digital implemented Signal Processors (DSPs). Two possible choices DSPs...
Abstract Growing demand for energy consumption worldwide has led to an increase in carbon emissions, which have significant effects on climate change. There is urgent need clean and renewable sources. However, most sources, such as solar wind, very high initial costs, especially when used a principal source. Distributed power generation using wind provides effective solution reduce the dependency conventional reliability quality of systems. A mixture distributed systems loads can then be...
Microgrids are the main building blocks of future smart grids. They provide a promising solution for integrating renewable energy sources and distributed power generation into The high penetration their intermittent nature have brought about significant challenges to control operation microgrids. In recent years, an enormous amount research has been conducted on microgrid dynamics, stability analysis, management, control. However, there limited effort integrate cutting-edge technologies...

Artificial intelligence methods such as fuzzy logic and particle swarm optimization (PSO) have been applied to maximum power point tracking (MPPT) for solar panels. The P-V curve of a panel exhibits multiple peaks under partial shading condition (PSC) when all modules do not receive the same irradiation. Although conventional PSO has shown perform well uniform insolation, it is often unable find global PSC. Fuzzy adaptive controllers proposed MPPT. However, controller became...
