Abstract

This paper is concerned with the linear unbiased minimum variance estimation problem for discrete-time stochastic linear control systems with one-step random delay and inconsecutive packet dropout. A new model is developed to describe the phenomena of the one-step delay and inconsecutive packet dropout by employing a Bernoulli distributed stochastic variable. Based on the model, a recursive linear unbiased optimal filter in the linear minimum variance sense is designed by the method of completing the square. The solution to the linear filter is given by three equations including a Riccati equation, a Lyapunov equation and a simple difference equation. A sufficient condition for the existence of the steady-state filter is given. A simulation shows the effectiveness of the proposed algorithm.  DOI: http://dx.doi.org/10.11591/telkomnika.v11i11.3523

Abstract

A popular hypothesis regarding legged locomotion is that humans and other large animals walk and run in a manner that minimizes the metabolic energy expenditure for locomotion.  Here, we just consider the walking gait patterns. And we presented a hybrid model for a passive 2D walker with knees and point feet. The dynamics of this model were fully derived analytically. We have also proposed optimized virtual passive and virtual coupling control laws. This is also a simple and effective gait-generation method based on this kneed walker model, which imitates the energy behavior in every walking cycle. The control strategy is formed by taking into account the features of mechanical energy dissipation and restoration. Following the proposed method, we use computer optimization to find which gaits are indeed energetically optimal for this model. And we also prove some walking rules maybe true by the results of simulations. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2612

Abstract

To obtain efficient maximum power point tracking operation under varying and steady state environmental conditions which is based on Ant Colony Optimization (ACO) combined with Particle Swarm Optimization (PSO) that controls an interleaved DC-DC converter connected at the output of PV array and maintains a constant input-power load. The operation of maximum power point tracking is to adjust the power interfaces so that the operating characteristics of the load and the photovoltaic array match at the maximum power points. The simulation is based on the computed algorithms which show very good perspectives. The searching routine is done in less than 15 steps and takes less than 50ms. The tracking accuracy is better than those found in conventional methods. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7900

Abstract

This correspondence considers multiple-input single-output (MISO) wireless systems with equal gain transmission (EGT) at the transmitter and maximum ratio combining (MRC) at the receiver. In such systems, the receiver feedbacks the elemental phases of beam-forming vectors to the transmitter. Due to finite feedback rate, the elemental phases of beam-forming vectors have to be quantized effectively before feedback. This correspondence makes use of the trellis-coded quantization (TCQ) to quantize elemental phases of beam-forming vectors. The principle of TCQ and its application to phase quantization are introduced in detail. Representative simulation results are given to verify the superiority of TCQ phase quantization over other quantization schemes. The research results can be applied to the image information such as wireless transmission systems on many agricultural robots to work together, improve the efficiency and reliability of information transmission. DOI: http://dx.doi.org/10.11591/telkomnika.v10i7.1579

Abstract

Optimization of agricultural practices for enhanced crop yield is considered to be essential phenomena for the countries like India. In order to strengthen the economy and also to meet the food demand for the exponentially growing population, optimizing the agricultural practices has become necessity. In India, weather and geographical conditions are highly variable and were thought to be the major bottleneck of agricultural practices to achieve improved crop yield. Agricultural practices in India are facing many challenges such as change in climatic conditions, different geographical environment, conventional agricultural practices; economic and political scenario. Economic loss due to the lack of information on crop yield productivity is another major concern in the country. These hurdles can be overcome by the implementation of advanced technology in agriculture. Some of the trends observed are smart farming, digital agriculture and Big Data Analytics which provide useful information regarding various crop yields influencing factors and predicting the accurate amounts of crop yield. The exact prediction of crop yield helps formers to develop a suitable cultivation plan, crop health monitoring system, management of crop yield efficiently and also to establish the business strategy in order to decrease economic losses. This also makes the agricultural practices as one of the highly profitable venture. This paper presents insights on the various applications of technology advancements in agriculture such as Digital Agriculture, smart farming or internet of agriculture technology (IoAT), Precision Agriculture, Crop Management, Weed and Pest control, Crop protection and Big data analytics.

Abstract

DEVS is a hierarchical and modular system descriptive method. However, it cannot describe dynamic process and relationship of system members. This article has proposed a way to extend UML using stereotype, making it suitable for simulation modeling. To build a modeling tool, we defined atomic model class and coupled model class, both of which are in line with not only DEVS’s hierarchical and modular requirements but also UML’s object-oriented characteristics. At last, we use the tool to analyze and build UML models for a dynamic logistics system, the container berth system, making it easier to implement on simulation platform. DOI: http://dx.doi.org/10.11591/telkomnika.v11i4.2397

Abstract

A robust method for panorama view reconstruction from multiple viewpoints of the large-scale object is presented. The desired object must be acquired from multiple viewpoints. The information of the feature points of an object is obtained by establishing correspondence between views. We present a robust method based on image mosaicing approach and panorama synthesizing. First, the feature of each object is extracted. Then the corresponding feature points of an object between the images are estimated. The different of minimum threshold value between two images is computed. After that, the full-view of an object is reconstructed by integrating two images based on image mosaicing approach.This research describes how to establish feature correspondences between images accurately and effectively. Image registration technique provides an initial estimation for establishing feature correspondences of point features. The linear solution with the reliable correspondences makes the computation of the geometric transformation between two images, called homography. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1178
