Projeto e concepção de um quadcopter utilizando o controle PID

The present work refers to the design, conception and development of a quadcopter based on PID controllers, a widespread microcontroller on the market was being implemented, the Arduino. Also made use of LabVIEW programming tool from National Instruments company for the quadcopter control and telemetry. For the control, LabVIEW software acquired the joystick commands, making the necessary adjustments to the perfect interpretation by microcontroller on the quadcopter and adjusts the parameters of PID controllers. For telemetry, data relating to quadcopter behavior are received, interpreted and presented in an intuitive user interface. In the first part of this graduate work presents the theoretical background on the subject, with a brief history about the quadcopters, followed by the main projects in the academic and commercial matters. Also are presented the theories of communications used in the design and PID control. Then an overview of the dynamic and mathematical model is demonstrated. Having done this, the physical and computer components required to complete the project are showed and the results are achieved consequently. Finally, a conclusion is made taking into account the results obtained. In this work will be presented the PID control of quadcopter translational movements only to roll and pitch movements

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

Controle de Acesso utilizando Arduino, banco de dados MySQL e LabVIEW

The search for more reliable security systems and information management of these systems is leading to a growing progress in new technologies investments that allow the implementation of equipment with a high level of reliability, but also have an agile and practical operation. This led people to turn increasingly looking for home automation systems, enterprise and industry for the automation and integration of their systems. The identification by radio frequency is very widespread today for ensuring both agility in handling records data, the reliability of their identification systems, which are increasingly advanced and less susceptible to fraud. Attached to this technology, the use of the database is always very important for the storage of information collected, the area where the MySQL platform is widely used. Using the open source Arduino platform for programming and manipulation of RFID module and LabVIEW software for the union of all these technologies and to develop a user-friendly interface, you can create a highly reliable access control and agility places a high turnover of people. This project aims to prove the advantages of using all these technologies working together, thus improving a flawed system effectively safety, cheaper and quicker

Planejamento e controle da produção: reestruturação no layout de apertadeiras eletrônicas em uma linha de produção do ramo de autopeças

In industrial plants, there is a department responsible for planning the use of productive resources to find the best possible way to set out plans in strategic, tactical and operational levels. This department is known as PCP or PPCP, which means Planning and Production Control and Planning, Programming and Production Control, respectively. This work presents the use of some of the tools from this department, in particular the Aggregate Production Planning, to propose a new layout of electronic nutrunners for an auto parts industry output line. Through some process indicators analyzes, was identified some productivity losses. The higher loss rate occurred by the electronic nutrunners breaking, and so this work was focused in these devices. Some premises were adopted for the use of electronic nut runners, setting an ideal cycle time for the operation of the production line and making calculations to define the minimum amount of electronic nutrunners to find the production demand without damaging the equipment. With this work we observed that a relevant factor for the constant breaks of electronic nutrunners is because these are working with overload, in other words, the amount of installed equipment is not enough to supply the demand without failures

Gerenciamento na construção civil - planejamento e controle: estudo de caso no planejamento físico de um empreendimento imobiliário

Given the high competitiveness in the construction industry, businesses became necessary in a management which reduce costs and delivery times, and is fundamental to running a compatible planning with the magnitude of each work order is the same make feasible the executor. When it comes to planning, one is including both the physical planning of the work, time and duration of the events, as well as the preparation of the cost thereof. There are numerous ways to run the management of works, then it is necessary, in most cases, the planning experience, in previous works, the engineer in charge, because with it he should know what strategy to take the work skirt as planned and designed. For a complete and efficient management, an initial study hard to prepare the physical and financial planning it is necessary, in order to make it real and consistent throughout the execution of the work. It is necessary also a hard monitoring of both the physical and the financial schedule in order to what was initially planned to be completed as close as possible. This paper shows a case study which uses some ways to the management be held with the course of planning, medium and short term, as well as the preparation of the initial budget of the work. Will also be presented as is performed physical planning of a real estate work
