An artificial visión system based in the BOF method implemented in a FPGA device is presented to locate and recognize rigid work pieces within an experimental workspace area, previous location is not known by a manipulator robotized element in order to grasp it and perform an assembly process (peg in hole) in real time. As the processor element a Nexys 4 development electronic FPGA card is used with Hardware Description Language (HDL) platform for its programming, and the OV7670 camera from OmniVision is used as the imaege acquisition device. Data is acquired, conditioned and processed to get information about location and feature recognition characteristics for the assembly process within an experimental manufacturing cell environment containing an educative robot manipulator of 6DOF. Two methods were used for comparison results resulting 50% success assembly for the first one when only using primitive descriptors of area an centroid and 96% success when BOF method was using. An assembly process was performed integrating the method in a single FPGA device. Having performed real time image acquisition and processing actions, the results shows the possibility of using this method for concurrent and fast assembly applications.

The three-phase to medium frequency single-phase direct conversion with the Modular Multilevel Converter for Solid State Transformers involves control and modulation challenges due to the switching devices limitations. The use of Nearest Level Control (NLC) as a modulation technique to properly synthesize medium frequency voltages at the output is proposed on this paper, paying special attention to the arm inductors effect at medium frequency operation. Using NLC results in low distortion medium voltage and medium frequency single-phase output, achieving good controllability and reaffirming the suitability of the converter for its application in Solid State Transformers.

This paper deals with a predictive current control at fixed switching frequency for a grid-connected neutral-point clamped voltage source converter. The method applies three voltage space vectors at every sampling period and the duty cycles are computed using the cost function. The current errors along with the voltage drift of the neutral-point are the control criteria, whereas the switching frequency is constant and defined by the sampling period. Simulations results validates this proposal showing quick response and good current tracking.

The objective of this project is to design and development a Virtual Instrumentation System (VIS) applied to automate tensile tests to characterize materials in Electromechanical Engineering Laboratories. The developed system is based on a robust hardware architecture, data acquisition has high levels of accuracy, and the virtual instrument automatically determines the test curve and the test characteristic. The developed system consists of three modules: the Sensor Module, which is composed of the load cell and the strain gauges; the Data Acquisition Module, which is composed of the Compact FieldPoint device and an expansion card for conditioning signals from strain gauges; finally the Software Module which is composed of parameter calculation algorithms and data display algorithms. For the evaluation of the VIS was carried out two experiments: 1) experiment with the initial testing machine, equipped with analog meters and manual processing of the measured data; and 2) experiment with the final testing machine, equipped with the VIS, which automatically acquires and processes the test data. Then the results of experiment 1, experiment 2, and the manufacturer’s data were compared. As obtained results: VIS shows a better definition of the stress-strain curve; the maximum error between the values obtained by VIS and the data obtained in the traditional form using manual calculations is equal to 4.6 %; and, the reliability of the tensile test has been improved from 89.5% (without VIS) up to 95% (with VIS).

With the passing of time, learning methodologies have been changing, focusing on the technology as a mean to facilitate the learning process. Although the idea of a blended learning (B-learning) takes more strength every day, the concern that arises is how to take advantage of the benefits of traditional “face to face” teaching with that which only uses technological resources. A relevant issue is that the specialty courses, especially those of last courses of the formation process, have a low number of students. The proposal of this work is to create a collegiate room, which can be joined by students from different institutions, who will participate in face-to-face or remote mode, where each class will be in charge of a professor from one of the institutions, with students who will participate in face-to-face, while others will participate remotely, but, with at least one professor, in charge off support the development of the remote class in person. Practical laboratory activities can be also performed in a remote way. This modality will allow more time for each professor to work in collaborative way and it will make better use of the available laboratory equipment, both in quantity and time of use.

The recognition of objects and the proper handling of them is a common problem in service robots. This article presents a set of computational vision algorithms to improve an object detection system using an RGBD sensor. Within this set of algorithms is the computational vision algorithm to identify a plane, a second algorithm to determine the position of an object and a third algorithm that performs the Principal Components Analysis to identify the orientation of the objects and to perform a correct manipulation. Several tests are presented that validate our approach. This group of algorithms is used by the service robot Justina at the upcoming RoboCup 2018 international tournament [1].

This paper describes a series of experiences in automation control that can be carried out by using a Remote Laboratory System implemented at the Universidad del Bío-Bío (UBB). Remote laboratories are increasingly used by universities to perform the practical activities, especially for control engineering education. This method allows using the laboratory resources more efficiently, as it growths the availability up to 24 hours a day, requires no extra time to practice assemble, and allows to share expensive resources with many students geographically separated from the laboratory setup. The aim of this contribution is to show, with practical examples, the potential of this methodology applied to the teaching of automatic control at the UBB with the Remote Laboratory Systems (”Sistema de Laboratorios Distancia”, SLD) developed preliminarily in the Universidad Central de Las Villas, Cuba. A scale model of coupled tanks made up by the Feedback Instruments Company was incorporated to the SLD at the UBB. Thus, a series of level control experiences were designed to validate the proportional, integral, and derivative actions effects of classic PID controllers. In addition, experiences to show the necessity of some practical changes on the classical PID were also developed as sensed variables filtering, anti-windup correction, and derivative action filtering.
本文介绍了在自动化控制方面的一系列经验,这些经验可以通过使用universsidad del Bío-Bío (UBB)实现的远程实验室系统来实现。高校越来越多地利用远程实验室进行实践活动,特别是控制工程教学。这种方法可以更有效地利用实验室资源,因为它增加了一天24小时的可用性,不需要额外的时间来练习组装,并且允许与许多地理上与实验室设置分开的学生共享昂贵的资源。这篇文章的目的是用实际的例子说明这种方法应用于古巴中央拉斯维拉斯大学初步开发的远程实验室系统(“远程实验室系统”)在UBB自动控制教学中的潜力。由反馈仪器公司制作的耦合罐的比例模型被纳入UBB的SLD。因此,设计了一系列水平控制经验来验证经典PID控制器的比例、积分和导数作用效果。此外,还开发了对经典PID进行一些实际更改的经验,如感测变量滤波,反上卷校正和导数作用滤波。

Microgrids are small-scale electric power systems that emerge as an alternative to solve the current problems of conventional networks. The main objectives that they pursue are the reliability, diversification of energy resources, reduction of carbon emissions, minimization of costs and the introduction of intelligent control techniques, which increase the dependence on communication networks. Some research related to communications in electrical networks has been developed, but few are related to the appropriate communication system, according to the control algorithm. This paper proposes the best architecture for intelligent microgrid applications based on latency, QoS, bandwidth and capital cost, to improve control and operation. In addition, the fundamentals of communications and control strategies are described. The results show that communication technology affects the control performance of intelligent applications and the smartness of the grid, which causes poor quality of service. This analysis is very useful for the grid planning and the developers, who can select the appropriate architecture according to their needs.

In this paper, signal processing based in colours is used together with orthogonal polynomials that serve as a model to identify the system: signal noise to characterize geographic images that may be subject to climate changes and that often satellite images require processing with a certain approximation to identify areas of high sensitivity. For this purpose we model the signals and their colour using orthogonal polynomials. For that we use the criterion of polynomial expansion starting from a model of series of nonlinear integrals. We apply the model to an example that specifies the colour scale. We associate a colour to a portion of space according to the polynomial and its coefficients and kernels denote the intensity of the colour.

We present an advanced low-cost computational microscope based on simple components such as a cheap objective lens, a LED illumination matrix and 3D-printed parts. By implementing the Fourier Ptychographic Microscopy (FPM) technique onto a raspberry PI, we are able to acquire and synthetically produce images with wide field of view and high resolution. We present preliminary results, with the aim that at the end of this project, a low-cost kit will be presented to the community with assembly diagrams, 3D models and the FPM algorithms developed as a fully integrated system, so that it can be used and configured with relative simplicity such as in schools.
