Controle fuzzy de um motor dc utilizando sistema de aquisição de dados e o matlab

The present work develops a fuzzy inference system to control the rotation speed of a DC motor available in Degem Kit. Therefore, it should use the fuzzy toolbox of Matlab in conjunction with the data acquisition board NI - USB - 6009, a National Instrument’s board. An introduction to fuzzy logic, the mathematical model of a DC motor and the operation of data acquisition board is presented first. Followed by the controller fuzzy model implemented using Simulink which is described in detail. Finally, the prototype is shown and the simulator results are presented

Introdução à identificação de sistemas utilizando o System Identification Toolbox do MATLAB em conjunto com o Arduino para o laboratório de controle linear

The education designed and planned in a clear and objective manner is of paramount importance for universities to prepare competent professionals for the labor market, and above all can serve the population with an efficient work. Specifically, in relation to engineering, conducting classes in the laboratories it is very important for the application of theory and development of the practical part of the student. The planning and preparation of laboratories, as well as laboratory equipment and activities should be developed in a succinct and clear way, showing to students how to apply in practice what has been learned in theory and often shows them why and where it can be used when they become engineers. This work uses the MATLAB together with the System Identification Toolbox and Arduino for the identification of linear systems in Linear Control Lab. MATLAB is a widely used program in the engineering area for numerical computation, signal processing, graphing, system identification, among other functions. Thus the introduction to MATLAB and consequently the identification of systems using the System Identification Toolbox becomes relevant in the formation of students to thereafter when necessary to identify a system the base and the concept has been seen. For this procedure the open source platform Arduino was used as a data acquisition board being the same also introduced to the student, offering them a range of software and hardware for learning, giving you every day more luggage to their training

A implantação do Programa um computador por aluno - UCA na Escola Municipal Maria Antonieta Alfarano, em Salvador

A educaçao atrelada as tecnologias podem trazer ganhos significativos a sociedade. A relaçao entre as duas pode promover efetivamente inúmeras transformaçoes no contexto social e cultural dos alunos da Rede Municipal de Ensino de Salvador. Podendo ser as tecnologias digitais responsáveis por oportunizar uma imersao nas redes de comunicaçao e informaçao e novos modos de ensinar e aprender. Neste artigo, discutimos as açoes desenvolvidas na escola Municipal Maria Antonieta Alfarano, a partir do Programa Um Computador por Aluno - ProUCA. Com as discussoes, refletimos acerca da implementaçao do programa, do acompanhamento da Secretaria de Educaçao (SMED) e da realizaçao das atividades desenvolvidas no cotidiano escolar. O processo de inserçao de políticas públicas de tecnologia e as lacunas oriundas das açoes da Secretaria e Ministério da Educaçao (MEC) também sao abordados no texto. Foram consideradas na análise a proposta de formaçao desenvolvida pela Universidade Federal Bahia (UFBA) e sugeridas e acompanhadas pelo Núcleo de Tecnologia Municipal (NTM). Contudo, foi possível verificar que é viável promover integraçao, socializaçao e acesso as tecnologias e assim, implantarmos a cultura digital nas escolas da rede, promovendo novas práticas pedagógicas e novas formas de aprendizagens

Auxílio a tomada de decisão na inclusão de sobressalentes de manutenção em estoque utilizando um sistema especialista fuzzy

In the current economic scenario of constant changes, industries seek to increase their profitability decreasing inventory levels. Maintenance and maintenance management, combined with the inventory management of spare parts, has assumed a position of competitive advantage in business. Stock only what you need has become a difficult decision for managers, who are faced with the lack of models and criteria to assist this decision-making. This work proposes a method which supports decision making, on a MATLAB modeling, using criteria established by an expert and his maintenance workers team, focusing on no regular demand of spare parts. The proposed model was adequate to the needs of the company and the maintenance manager in the decision on the storage

Modelagem e simulação do mecanismo biela manivela e análise estrutural de biela automotiva

Nowadays, the automotive industry is working to optimize the design of engines, in order to reduce the fuel consumption with acceptable efficiency ratio. This undergraduate thesis is aimed at perform a kinematic/dynamic analysis of a slider-crank mechanism that is part of a four stroke internal combustion engine, the same engine that was used in the analysis described by Montazersadhd and Fatemi (2007). Two algorithms were developed based on Kane’s method to calculate velocities and accelerations of the mechanism bodies, and provide the acting forces at connecting rod joints. A SimMechanics model was developed to simulate the engine, and monitoring the same parameters that were calculated with the algorithms. The results obtained with both approaches were satisfactory and showed good agreement with the values provided by Montazersadhd and Fatemi (2007). The obtained results showed that the axial component of the rod joint efforts was caused by the pressure exerted on the piston head,whereas the radial component was related with the action of inertia loads. Besides, this thesis presents a connecting rod assembly mesh that is going to be used for static and fatigue finite element analysis in the future

Estimação do número de internações por doenças respiratórias utilizando lógica fuzzy tipo-2 intervalar

In this work was developed a fuzzy computational model type-2 predictive interval, using the software of the type-2 fuzzy MATLAB toolbox, the final idea is to estimate the number of hospitalizations of patients with respiratory diseases. The interest in the creation of this model is to assist in decision makeshift hospital environment, where there are no medical or professional equipment available to provide the care that the population need. It began working with the study of fuzzy logic, the fuzzy inference system and fuzzy toolbox. Through a real database provided by the Departamento de Informática do Sistema Único de Saúde (DATASUS) and Companhia de Tecnologia de Saneamento Básico (CETESB), was possible to start the model. The analyzed database is composed of the number of patients admitted with respiratory diseases a day for the public hospital in São José dos Campos, during the year 2009 and by factors such as PM10, SO2, wind and humidity. These factors were analyzed as input variables and, through these, is possible to get the number of admissions a day, which is the output variable of the model. For data analysis we used the fuzzy control method type-2 Mamdani. In the following steps the performance developed in this work was compared with the performance of the same model using fuzzy logic type-1. Finally, the validity of the models was estimated by the ROC curve

Estudo sobre qualidade de voo no modo longitudinal da aeronave e análise do critério de largura de banda

The flight quality describes the skills of the pilot realize a given task and its difficulty to perform it. Flight quality criteria provide a valuable reference for the designers during the requirements definitions phase and to develop them during the phase of flight testing. These criteria were taken important for the development of a fly-by-wire system. There are several flight quality criteria and this work analyzes the bandwidth criteria, this is evaluated according to a model an aircraft using the SIMULINK/MATLAB. In addition, the paper also describes in detail what is a flight quality criteria and shows an overview of the bandwidth criteria
