Abstract

For the high performance drives the artificial neural network based Induction motor is proposed. During the load variation, the performance of the Induction motor proves to be low. Intelligent controller provided for controlling the speed of induction motor especially with high dynamic disturbances. An effective sensorless strategy based on artificial neural network controller is developed to estimate rotor’s position and to regulate the stator flux under low speed, helps to track the motor speed accurately during the whole operating region. The overall combination of this setup is simulated in the MATLAB/SIMULINK platform. Finally an experimental prototype of the proposed drive has been developed to validate the performance of Induction Motor and the dynamic speed response of Induction motor with proposed controller was estimated for various speed and found that the speed can be controlled effectively.

Abstract

There exist a lot of image systems of different features in different field of view (FOV) in our real life. Multi-source fusion technology in different FOV is able to promote the performance of image acquisition system without additional investment in hardware equipment. With regards to multi-image fusion technology in different FOV, in this research a registration method combined with affine transformation and linear interpolation is proposed, which analyzes pre- and post- fused images from the temporal and spatial perspective for comparison, evaluates and compares the fusion result so as to testify the applicable feasibility of the technology. DOI: http://dx.doi.org/10.11591/telkomnika.v11i9.3229

Abstract

Fault recovery of distribution network is realized by operating switches to change topological structure of the network. The final destination of fault recovery is power loss minimization, fault isolation and power load transfer. This article has built the mathematical model of fault recovery considering constraints of node voltage, line capacity and power flow balance. The objective function is power loss reduction. Further, the genetic algorithm is used to solve the proposed model. The optimal network structure and recovered power load could be derived through calculation. Finally, the author complied the program with Matlab and tested it on the IEEE33 bus system. The simulation and analysis results have verified the effectiveness of the proposed method. DOI : http://dx.doi.org/10.11591/telkomnika.v12i3.4567

Abstract

Biometric cryptosystem provides a seamless connection between the biometrics and traditional password, and it represents a new development in the next generation cryptography. Even if the biometric cryptosystem is secure in algorithmic design, it may still be vulnerable to side-channel attack due to the physical leakage. To assess the possible side-channel attack on biometric cryptosystem, a secure biometric cryptosystem is designed and by measuring the energy consumption leaked. The simulation shows that the biometric cryptosystem can be extracted with bits of energy leakages. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1285

Abstract

Electric kick scooter field has become famous this lately, and become another solution for electric vehicle. Switched Reluctance Motor has been choosen as the propulsion system in this application due to the advantages of this motor. Meanwhile, the issue of lack experience in electrical motor design is one of the hollow subjects in machine design field. Through design aspects, the Switched Reluctance motor is developed using a simple technique which is coefficients method. This method is to provide the easiest ways for other non-academic designer for those who has lack experience in motor design. A set of a coefficient to determine motor dimension is being set. Then, this technique will be refered to the existing analytical method to provide a design guideline and to validate this coefficient as the quick references to design the SRM. The aim is not to make a comparison between the methods but intend to provide another easiest solution to design the SRM motor. The modelling has been test using RMxprt tools The expectation from this method is the outcomes will be compatible with existing design.

Abstract

Step counter, being an active area of human daily physical activity, is an essential role in human activity determination research. As the current smartphones come with many different sensors and powerful processing capabilities, the step counting using built-in sensors in a smartphone is increasingly becoming a vital factor among many researchers. However, the step counting with a smartphone has still challenging due to many different walking behaviors and mobile phone positions. In this study, we introduce a more reliable step counter’s technique using Accelerometer sensor in a smart phone. The objective of this study is to get the accurate steps of three different walking activities in four different mobile positions. In order to achieve this, a new reliable technique based on peak is attracting considerable in our work using average acceleration. The experimental result shows 99.02% as an overall step counting performance that the proposed method reliably detects the steps under varying walking speed in different devices modes. This result is encouraging to facilitate among of the complex walking activities using built-in sensors in smartphone.

Abstract

This paper presents the performance of a three-phase current source inverter (CSI) in island mode voltage-controlled operation. Simple converter structure, low switching count and inherent boosting capability among the features offered by CSI. However, less investigation has been done with regards to the performance of CSI especially on its control system for island and grid-connected photovoltaic system. Thus, this study aims to investigate the suitability of proportional-integral (PI) and proportional-resonant (PR) control including their dynamic equations and state-space modeling. The results show that both controllers able to perform satisfactory in achieving zero steady-state error and balanced sinusoidal output voltage and current. PI control is superior in fast response time and excellent harmonic rejection than inverter using PR control PR control on the other hand, able to give more robust performance during imbalance occur than PI control due to individual control of the phases. This study may becomes one of the references with regard to current source inverter for early career researchers. as All results presented in this paper are verified with varying operational parameters in MATLAB/ SIMULINK platform.

Abstract

Opportunistic spectrum access (OSA) is a key technique enabling the secondary users (SUs) in a cognitive radio (CR) network to transmit over the “spectrum holes” unoccupied by the primary users (PUs). In contrast to OSA, with spectrum sharing (SS) is allowed to transmit regardless of the PU’s on/off status, provided that the resulting interference to PU is kept below a predefined threshold. In this paper, we focus on the threshold detection algorithm study for spectrum sharing, which aims to get the SIR of the PUs as quickly and precisely as possible. We propose a dichotomy algorithm with lower complexity and more quickly in contrast to the traditional full search algorithm. Numerous simulation results are provided to validate the proposed algorithm. DOI: http://dx.doi.org/10.11591/telkomnika.v12i6.5489

Abstract

The judgment of metal rod buffer system bonding quality depends on the bond of the metal rods with the surrounding medium. System bonding area will lead to different reflection amplitude. Compared the simulation with the experiment, it can be concluded that different bonding area can measure bond quality, i.e, the greater the bonding area is the more excellent bonding quality will be. This conclusion provides the basis for the system ultrasonic testing. DOI: http://dx.doi.org/10.11591/telkomnika.v11i3.2193

Abstract

The growth-site quality is one of the essential information needed to support sustainable forest management particularly in forestry planning. This paper describes the development of a site-quality class of Nypa vegetation by considering the biological and physical factors. The main objective of this study is to develop a discriminant model and to find out major factors that may be used to predict the quality of Nypa growth-sites.The model was developed using variables either measured on UAV images or from field measurement, namely soil texture (X1), water salinity (X2), water pH (X3), crown closure (X4) and stand density (N) measured on the UAV image (X5). The study found that the site quality of Nypa could be indicated by the variation of its biomass content. Then, it was concluded that the major factors that affect the site quality are the soil texture (X1),water salinity (X2),and water pH (X3) with 78.3% of overall accuracy.
