The article considers approaches to partial eigenvalue assignment in second order descriptor systems using proportional plus derivative plus output feedback controller. The impulse elimination approach by output feedback control is addressed by combining the eigenstructure and the closed-loop system's finite eigenstructure. With a base in the desired eigenstructure, the gains controller's parametric formulations doing the closed-loop system impulse-free and assigning the finite eigenstructure are referred. The computational simulation result is provided to verify the effectiveness of the proposed method. This study presents an approach to partial eigenvalue assignment for the descriptor system where an algorithm is presented for calculated the output feedback matrix by the Sylvester equation. Sylvester equations present the theorems. Two algorithms are implemented using the Sylvester equation, and examples were presented with finally their conclusions.

The adjustment of the DC-link voltage in proportion to the speed, except at very-low frequencies, can potentially overcome torque limitations in MMC-based AC motor drives. However, the grid- and motor-side converter require be equipped with FB cells. To reduce this requirement, this work proposes the use of Hybrid MMC converters. To further improve performance at very-low frequencies, it is proposed that the intermediate link, between the grid- and motor-side converter, be operated as AC link, instead of DC-link, but only at low speed. An AC link voltage having a relatively small amplitude and frequency, compared to nominal values of the motor, is sufficient to maintain the ripple as low as that of the nominal speed. Results shows that 50% and 25%, of the total number of cells in the grid- and motor-side converter, respectively, are required to be of the FB type. This may be a practical solution for medium power drives that require to operate at very-low frequencies without torque restrictions.

Rurality has traditionally been a factor of marginalization in education, and it persists as a barrier that affects the progression of students in the educational system. Educational Robotics (ER) has its origins in Papert's constructionism, it is not simply assembling robots, it is a very versatile learning tool that allows working in different areas of knowledge. The objective of the article is to present information regarding the use and acceptance of ER by students from rural establishments in the Región de Atacama; The work methodology used was proposed sequentially and divided into groups of activities: i) Hypothesis Approach, ii) Definition of Methodology and Assessment Instruments, iii) Development of ER Activities, iv) Documentation and v) Analysis of Results. The information obtained after the results shows that the efficient and effective use of ER depends to a great extent on the level of ownership that the participants present in this regard, quickly becoming accustomed to the robot, carrying out participatory interactions between peers and oriented towards learning and solving problems.

In this paper, a 57-level asymmetric multilevel inverter is proposed with less number of devices and sources. Working process of symmetric and asymmetric structures are studied and tested using MATLAB. Proposed asymmetric structure is compared and analyzed against other multilevel inverter topologies. Resistive load and reactive load is considered for symmetric and asymmetric inverter simulation. Further, symmetric and asymmetric configurations are compared in terms of harmonic content. Proto-type development is carried out for the fifty-seven-level asymmetric inverter and the test results are presented. From the results, it is concluded that both symmetric and asymmetric structure yield low harmonic output waveforms.

The integration of distributed generation (DG) in distribution networks has grown in recent years due to its ability to increase the efficiency of the system. One of the aspects that increase this efficiency provided by GD is the reduction of electrical losses. In this study, simulations of different cases are carried out to assess the losses of active power depending on the location and the level of penetration of distributed photovoltaic generation. The study is divided into two stages. In the first one, the objective is to verify the impact of the GD location on the technical losses of the distribution system. Based on the best location obtained, the technical losses are evaluated in relation to the level of penetration of these sources in the system in the second stage. In the latter, five possible penetration scenarios were considered and the behavior of technical losses in the distribution systems was analyzed. The simulations are performed using OpenDSS software and are applied for the standard IEEE 34-node distribution system. The results demonstrate that the insertion of distributed generation can contribute satisfactorily to the reduction of technical losses in energy distribution systems, as long as they are well allocated and with an optimized penetration level.

Conditioning the output voltage of Piezo-electric crystal is very important for Energy harvesting process. The productive method to collect the energy from the framework for the most part relies upon its interfacing hardware. It is important to portray and streamline the interfacing circuit for expanding the yield power. The circuit parameters such as duty cycle, switching frequency, inductance and load resistance have been portrayed and streamlined to improve the effectiveness of the overall system. A higher order Cuk Converter is proposed for integrating piezoelectric energy harvester (PEH) and energy storage elements or load directly. The circuit has been simulated using Matlab Simulink. The supply voltage of the piezoelectric transducer is an impulse force and the regulated output DC voltage is obtained as 1.3V from a single crystal (PZT-5A) and a total of 5.2V is obtained by cascading five crystals. The output voltage of the crystal stack is rectified and boosted using Cuk converter. The operating range of the system is increased by employing PI controller, Sliding mode controller and Hysteresis controller.

Distributed power generation together with microgrids and renewable energy have brought the problem of power generation and electric system stability. These kinds of grids have shown problems related to the frequency and amplitude voltages. In effect, the literature shows variation up to 100% on the grid frequency, leading to carefully design the equipment that is connected to these grids. This paper studies the frequency variation, the sag, and swells effect on power converter by using the two most used topologies, the power converter as rectifier and inverter with their respective first order and second order filters respectively. The results show the large effect on the power converters and therefore demonstrate the importance of considering the frequency on the control design, since the entire operating region is affected.

This paper presents a method of characterizing Load Distribution Networks for peak load pricing, using load profiles sampling from consumer units, commercial distribution database, and climate variables. It is considered rate subgroup, consumer class, and temperature as exogenous variables. The temperature data considered in the model are directly related to load destined for cooling and heating. Modeling is supported by Artificial Neural Networks methodology with Multi-Layer Perceptron architecture and Back-Propagation training algorithm. In a real case study, load profiles in the Brazilian electrical system, from September 2013 to August 2014, are compared with clustering models traditionally used in load profile characterization to peak-load pricing. The model provides a forecast error equivalent to 5.46% in the distribution sector, lower than the forecast error of 23.04% for the clustering model and load typologies.

The present work facilitates the monitoring of the nutritional composition of the cultivation soil by identifying nutrient deficiencies through image recognition of banana leaves using a convolutional neural network trained with transfer learning and fine tuning. An original dataset of photos was used in this research, which is composed of healthy banana leaves images, and leaves with known deficiencies of nitrogen, potassium, and phosphorus. Subsequently, an augmentation is performed to this dataset through linear transformations and the resulting images were pre-processed in different color spaces to be used as inputs to the neural network. It was possible to obtain a model with high precision that could be validated through different metrics. Finally, a prototype of a web platform was developed so that the system could be accessed by farmers.

In this study, a new implementation of the slime mould algorithm (SMA) is proposed to find the optimal parameters of proportional-integral (PI) controller and enhance the frequency stability in a two-area interconnected power grid combining thermal generator unit and photovoltaic (PV) system. Moreover, the design process of the considered power system takes the maximum power point tracking (MPPT) of the PV into its consideration. Furthermore, a time-domain based on the integral of time multiply absolute error (ITAE) is recognized for the robust design of the PI controller parameters exploiting the proposed SMA. The comparative results demonstrate the robustness of the proposed SMA-PI controller among all control methods (e.g. WOA-PI controller, GA-PI controller, and FA-PI controller) in terms of maximum undershoot, maximum overshoot, and maximum settling time under different operating condition (system parameters variations, and load disturbance).
