Item type:Publication, Grid-connected photovoltaic system with maximum power point tracking using self-organizing fuzzy logic controller(2005-01-01); This paper presents the design of a controller for the maximum power point tracking of a grid-connected photovoltaic energy conversion system. A boost converter is used in the system to deliver the output from the solar array to DC-AC inverter, and feed the power into the AC grid. A self-organizing fuzzy logic controller is introduced for the tracking algorithm. The duty ratio for the operation of the boost converter is optimally adjusted in such a way that the maximum power point, which normally varies according to the environment, can be achieved. We demonstrate via the simulation results that our proposed technique outperforms over the conventional fuzzy logic controller in terms of tracking speed and transient response. Furthermore, the algorithm implementation can be done using a look-up table, hence a high-performance, cost-effective real-time maximum power point tracking can be simply realized. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Adaptive array processing unit based on direct data domain least square approach using conjugate gradient method(2007-12-01); ; Sarkar, Tapan K.This paper presents the design of an adaptive array processing unit based on direct data domain least square approach using conjugate gradient method. The unit was applied for operation in the adaptive antenna scenario. The efficient architecture for FPGA implementation using fixed-point operation is present. The simulations are shown to evaluate the performance of the proposed adaptive processing unit. Moreover, simulation results obtained from the unit using fixed-point operations also show a good agreement with the unit using floating point operations. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A novel fuzzy logic control technique tuned by particle swarm optimization for maximum power point tracking for a photovoltaic system using a current-mode boost converter with bifurcation control(2010-04-01); This paper presents a novel fuzzy logic control technique tuned by particle swarm optimization (PSO-FLC) for maximum power point tracking (MPPT) for a photovoltaic (PV) system. The proposed PV system composes of a current-mode boost converter (CMBC) with bifurcation control. An optimal slope compensation technique is used in the CMBC to keep the system adequately remote from the first bifurcation point in spite of nonlinear characteristics and instabilities of this converter. The proposed PSO technique allows easy and more accurate tuning of FLC compared with the trialand-error based tuning. Consequently, the proposed PSO-FLC method provides faster tracking of maximum power point (MPP) under varying light intensities and temperature conditions. The proposed MPPT technique is simple and particularly suitable for PV system equipped with CMBC Experimental results are shown to confirm superiority of the proposed technique comparing with the conventional PVVC technique and the trial-and-error based tuning FLC. © ICROS, KIEE and Springer 2010. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Beam-switching-assisted CMA initialization for handset adaptive antenna(2007-08-28); ; This paper presents two initialization schemes: phased array-assisted initialization and switched-beam element phased array-assisted initialization, for a constant modulus algorithm (CMA). Both techniques utilize a beam with maximum received power obtained by beam-switching of array antenna to initial CMA. The techniques can significantly improve convergence properties of CMA, which is employed for weight adjustment of an adaptive antenna system. The architecture of the proposed adaptive antenna system is illustrated to show the low-cost assistance for CMA initialization. Finally, simulation results are shown to evaluate SINR performance of the proposed techniques. ©2007 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Leaf Sensor for Stomata Transpiration Monitoring Using Temperature and Humidity(2018-07-02); Chongcheawchamnan, MitchaiThis paper presents a leaf sensor which was designed for stomatal transpiration detection. The sensor consists of a thermocouple, a humidity sensor and a programmed microcontroller. The thermocouple measures temperature difference between the leaf and its surrounding atmosphere while relative humidity of the atmosphere was recorded. The sensor design was verified with the standard tool and the image of stomata captured with a high-gain camera lens. From the experimental results, data collected from the developed sensor indicates the stomatal status. This proves the potentiality of the proposed sensor for stomatal transpiration detection. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Single-Frequency Sensor for Thick Rind Fruit Quality Assessment(2025-01-01); ; A sensor capable of estimating the dielectric properties of the outer and inner materials of a concentric dielectric sphere is essential for assessing the quality of thick rind fruits. This article presents a sensor design that operates at a single frequency and is straightforward. The underlying principle of the sensor involves transmitting a microwave signal to a concentric dielectric sphere with two power levels. The low-power signal yields backscattered waves from the outer sphere, while the high-power signal provides information about backscattered waves from both the outer and inner spheres. The sensor, which operates at a frequency of 10 GHz using cost-effective components, effectively detects defects in spherical-shaped fruits, e.g., mangosteens. The accuracy in classifying translucent mangosteens from normal mangosteens is 92.5%, enabling effective classification of defected fruits.
