This article presents the design of a fuzzy controller to stability analysis base on the convergence of the linguistic trajectory in the state of space, for an inverted car-pendulum system, the fuzzy controller is of the Mamdani type and, it consists of 25 rules, 3 input variables and each one is composed of five memberships functions. The inverted car-pendulum system is represented by a non-linear model, which is obtained from a linearized equivalent model under the consideration of small oscillations. Results are validated against a PID control base on the trajectory on the phase plane to evaluate the efficiency and effectiveness of the fuzzy controller. The dynamic behavior of the system of both controllers is obtained with a unit impulse input, the simulation of the control system is developed on the MATLAB / SIMULINK software using the FUZZY LOGIC TOOLBOX, which allows to perform test and simulations, and also it shows results of graphic form.

The hydrogen is an attractive energy carrier and electrolysis of water is the most efficient to H2 production process. The OER in the anode is the limiting reaction being the case of study. In the present work materials based on IrO2 and WO3 were developed in different mechanical mixing 100, 70:30, 50:50, 30:70, respectively, by means of a mechanical mixture from two chemical reduction syntheses. The IrO2 was obtained by 6.25 mM of IrCl3 dissolved in isopropyl alcohol by adjusting the pH with 1M NaOH and a 0.5 mol NH4OH reductant was applied by adjusting a basic pH of 13. The obtained precursor was filtered and calcined at 400 ° C for 1hr. WO3 was obtained from 10mM WCl6 dissolved in isopropyl alcohol and polyethylene glycol, generating a precursor of W (OH)x followed by a calcination process at 500 ° C for 1hr. The material was characterized by electrochemical techniques of CV, LV and EIS. The IrO2-WO3 (50:50) material has lower activation energy of overpotential at room temperature, and a maximum current density close to 20 mA /cm2 at 1.8V vs Hg/Hg2SO4.

In a company, income must exceed expenses for the business to be profitable. The choices a company makes about its energy sourcing and consumption can profoundly influence its cost of production. The purpose of this paper is to examine the energy consumption of the cutting tool of a lathe using a numerical tool CNC. This study was designed to examine the relationship between speed of cutting and the spectral modes of the power spectral density. This work shows the impact of the current for different cutting speeds, the results of this study indicate that the power spectral density of the current of cutting, may be more than enough to determinate the energy consumption of the manufacturing process. The main contribution of this paper is the experimental validation of the attenuation of higher order modes of the electrical current at metal cutting process. These results can be used in the design and tuning of the speed control of the cutting tool.

In the engineering design process, it is of particular relevance the problem statement that has to be solved to guarantee an optimal design. There is no general rule for this, and in the particular case of the synthesis of flat mechanisms, the solution strongly depends on the problem statement for the design or mechanism synthesis. The object this paper is presenting one proposal at synthesis problem of a four-bar flat mechanism for cartesian trajectory tracking. The mechanism synthesis problem is stated as a nonlinear optimization problem with non linear constraints. Four different approaches are considered in order to demonstrate the impact of the considered statement of the optimization problem for its solution. The solution of the four optimization problems is obtained by means of numerical calculations using genetic algorithms. The numerical results of the four optimization problem statemens are compared under fair circumstances and they depict the great influence of the initial problem statement for its solution.

This article presents the design, simulation and fatigue analysis of various aerodynamic profiles used in low power wind turbines. For this purpose, the model of a blade of a horizontal axis wind turbine with a nominal power of 5 kW is developed. The analysis of the lift, drag and power coefficients of the aerodynamic profiles was carried out with the XFLR5 software. The methodology used for the blade design is based on the interactions and convergence method called BEM. Also, to simulate the structural and aerodynamic part of the element, the QBlade program was used. With the main objective of ensuring that the fatigue safety factors mentioned in the IEC 61400 standard are achieved, the Simplified Load Model was applied. The maximum fatigue value of 21,421.66 N and the maximum flapwise moment value of 698.41 Nm were obtained.

A channel-type Fresnel surface was designed using the polynomial interpolation adjustment method. The experimental arrangement was composed of a metal complex, a high power LED lighting source, a cooling system and a Fresnel concentrator. The tests were done in a dark chamber, placing the compound at an effective focal distance from the reflected rays of the concentrator, for a time. By exposing the sample to the LED irradiation, its changes were registered in a UV-Vis spectrophotometer, obtaining an absorbance graph vs wavelength, the changes observed in the transition bands in displacement and intensity of the blue region to the red of the spectrum, confirmed the efficiency and usefulness of the Fresnel-type concentrator in the development of the photochemical reactor. This photochemical reactor has an advantage over commercial reactors, because it uses samples of compounds in small solutions, is portable, it can be implemented in university and pharmaceutical laboratories. The results were favorable, a low energy consumption was obtained, and a reduction of time in the molecular reaction process of the analyzed compound.

Electrical motors are indispensable machines in the industry, thus it is necessary to ensure that engineering students can develop speed and torque controllers, in a fast and efficient manner. One of the most commonly used motor control strategies is Field Oriented Control; however it’s implementation requieres highly-intensive math processing and a fast processor with robust hardware resources. Several related works have been published, but they are hard to replicate and use due to the aforementioned problems. In this article, the author presents a torque and speed controller for industrial servomotors by means of Direct Torque Control which is known for its speed and ease of implementation compared to Field Oriented Control. In addition, the MicroPython programming language is used on the new and novel ESP32 microcontroller, which allows greater design simplicity. Results were validated using simulations and a physical implementation, thus achieving adequate motor funcionality. This work will provide students and researchers interested in industrial motor control, a fast and effective implementation tool.

Simulation is a method by which you can test, experiment or predict results in a certain process, scenario or object without the risk of real consequences. The objective of this research is to demonstrate how simulation is one of the greatest tools in engineering, which is used to represent a process through another and makes it much simpler and more understandable. This simulation is, in some cases, almost indispensable. In the simulation work, a methodology for design, development and evaluation is proposed. It is based on the synergy of two apparently dissimilar fields of knowledge: software engineering on the one hand and modern learning theories on the other, but which converge on the generation of a desirable product: simulation software. This methodology is based on the application of existing rules in both fields. As a result we have the use of simulation software, as a numerical technique to conduct experiments in a digital computer. These experiments involve certain types of mathematical and logical relationships, which are necessary to describe the behavior and structure of complex real-world systems over long periods of time.

In the present work is shown the numerical simulation performed by means of finite element software (FEA) and the static mechanical tests using extensometric techniques for a wind turbine blade of 600W in accordance with the international standard IEC 61400-2. A NACA 4412 profile was used and the loads applied were selected according to the following load hypotheses described in the standard: normal operation, maximum thrust, immobilization with wind load and maximum exposure. A methodology was developed for both the simulation and for the laboratory tests, the data of the microdeformation measured by extensometry were also analyzed and compared with those obtained by the numerical simulation. Concluding that the analysis of finite elements is a key step prior to manufacturing that allows us to save resources and gives us parameters to perform both manufacturing and testing. Laboratory tests are necessary to ensure safe and reliable functioning of the blade during its useful life.
