  2. 2. Title and Introduction SIMULATION BASED IMPLEMENTATION OF DC-DC BOOST CONVERTOR USING FUZZY LOGIC CONTROLLER TO ENHANCE THE TEACHING AND LEARNING OF POWER ELECTRONICS COURSE. Introduction: The purpose of designing and development of multifunctional PIC microcontroller based trainer is to design such embedded system trainers which have different functions modules to be used for teaching and learning on one board. It will help the students of engineering and technical education to get in depth knowledge and practical hands on experience about programming and implementation of PIC microcontroller in various embedded systems applications. On very affordable price, students may even place this trainer board in their home made labs especially for technical education students trainings ,the trainer to be developed would support the good process of learning. This PIC trainer consist of ten on-board embedded modules including main board and programmer, and experimental Lab manuals for all embedded modules. © Embedded Computing Systems Research Cluster
  3. 3. Problem Statement The current curricular in technical universities and institutions are more theoretical rather than technical hands-on based, thus producing graduates who are unable to meet the ever-rising demand of industry for skilled engineers. The employment cost is ultimately increased, as the employers have to spend extra on providing the required training. The emphasis in the light of education policy is to have more hands-on practical rather than academic. The price range for fully equipped workstations that comes complete with microprocessor or microcontroller training kits is very high and also additional costs such as maintenance of the board should be taken into account. This contributes to the limited number of boards and the ratio of available board to the students in the lab come to be very high – 1:2 or 1:3, which may depreciate the effectiveness of the teaching and learning process, consequently, the time taken to complete the whole syllabus will lengthen and probably the objective of the module taught will not be achieved. Most of the technical courses are being taught by using modules, that are prepared by vendors with mostly low academic background. Hence, such modules are produced with fixed features and usually have constraints in adapting to the changing needs of a technical institution. © Embedded Computing Systems Research Cluster 3
  4. 4. Objective The objective of this Project is: To design a PIC based educational trainer that can support the teaching and learning of Microprocessor System or Embedded System Design. To integrate several embedded modules in one training board to facilitate the learning environment for the students of technical education. To provide the students with an opportunity to be familiar with software tools like compilers, simulators, chip programming software. To provide a high degree of flexibility of use, which will allow the trainer/lab board to be used in varying applications. © Embedded Computing Systems Research Cluster 3
  5. 5. Scope and Limitation PIC Trainer to be developed should support the decent process of learning and teaching, students can also bring this trainer from their labs and continue work at their own places. This project serves as a fundamental for the students to indulge actively in the development of embedded system It is intended that the module designed should be free from any firmware, meaning that it should be open to any program and configuration without having any firmware that could interfere with user programs. The best thing is that the development of the programs, compiling, and then the simulations are all carried out with the freely available software tool Microchip MPLAB. PIC Education Trainer for students is the best way to help the students improve their skills and in the meantime reducing the cost for universities. © Embedded Computing Systems Research Cluster 3
  6. 6. Theoretical Framework The theoretical framework that will be used in the study is the InputProcess-Output Model. In the IPO model, a process is viewed as a series of boxes (processing elements) connected by inputs and outputs. Information or material objects flow through a series of tasks or activities based on a set of rules or decision points.

  7. 7. Operational Definition There are many steps involved in the design and development of this training panel. The panel includes, one main PIC board which is integrated with various multi-functional embedded system modules. All the modules are prototyped, PIC Simulator IDE is used to simulate the interface between the target microcontroller and certain available module . Then, modules are also constructed on a breadboard and tested. The successful modules are then prototyped on a printed circuit board. Finally all the modules together with its running board are integrated and tested for their functionality. PIC microcontroller main board is the heart of this panel. It acts as the main processing units for all inputs and outputs. Various multifunctional embedded system modules are being controlled using Clanguage programming which is downloaded in the microcontroller. The modules are multi-functional and hence they are flexible in their operation, which can be modified using programming. © Embedded Computing Systems Research Cluster 3
  8. 8. LITERATURE REVIEW Hardware component's of PIC Microcontrollers: PIC microcontroller production counts are in the billions per year, and the controllers are integrated into many appliances we have grown used to, like household appliances telecommunication, automotive industry, aerospace industry, industrial automation. hardware can be classified as input or output. Inputs range from simple switches to complex analog sensors which measure physical values and (ultimately) convert them into a corresponding voltage. Outputs encompass primitive LEDs as well as sophisticated actuators. Switch/Button : The button is one of the simplest input elements. It consists of two contacts which are connected if the button is pressed. So if one of the contacts is connected to for example GND and the other is connected to the microcontroller input and to VCC through a pull-up resistor (either internally by the microcontroller. Matrix Keypad: The matrix keypad consists of several buttons which are arranged in a matrix array. Potentiometer: The potentiometer is a variable voltage divider. It has three pins: Two for the input voltages Ua and Ub, one for the output voltage Uz. Depending on the position of a turning knob, Uz is somewhere within [min{Ua, Ub}, max{Ua, Ub}]. The correlation between the position of the knob and Uz can be either linear or logarithmic. © Embedded Computing Systems Research Cluster 3
  9. 9. LITERATURE REVIEW Hardware component's of PIC Microcontrollers: LED: The LED (light emitting diode) is the most basic output element. Its form and color vary widely to accommodate a wide variety of applications. The color of a LED is determined by the chemicals used for it. Common colors are red and green, but yellow, orange, blue and white LEDs are also readily available, as well as LEDs emitting light in the infrared or ultraviolet bands. Numerical display: A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot-matrix displays. Seven-segment displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying numerical information. Motors: Electric motors use electric energy to achieve a rotary motion. There are two basic principles which are used to create rotary motion in electric motors: the Lorentz force and magnetic attraction.  DC Motor: DC motors use DC voltage to achieve rotary motion. They have two pins with which to control the speed and direction of their rotary motion.  A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft rotation. Every revolution of the stepper motor is divided into a discrete number of steps, in many cases 200 steps, and the motor must be sent a separate pulse for each step. © Embedded Computing Systems Research Cluster 3
  10. 10. PIC Based: The main advantages of using the PIC are low external part count, a wide range of chip sizes (now from 5-pin up!) available, nice choice of compilers (assembly, C++, BASIC, etc.) good wealth of example/tutorial source code and easy programming. Once bought, the PIC's program memory is empty, and needs to be programmed with code (usually HEX files) to be usable in a circuit. Those trainers they controller by PIC architecture they have very good outcomes and results because they are very efficient for educational and training on-board modules. PID Based: The basic function of a controller is to execute an algorithm (electronic controller) based on the control engineer's input (tuning constants), the operators desired operating value (set point) and the current plant process value. They are expensive trainers and only cover some specific operation and not interface with any module. PLC Based: PLCs based trainers are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. These trainers are used for industrial robotics and automation. Microcontrollers: Microcontrollers may use four-bit words and operate at clock rate frequencies as low as 4 kHz, for low power consumption. They will generally have the ability to retain functionality while waiting for an event such as a button press or other interrupt; power consumption while sleeping may be just Nano watts, making many of them well suited for long lasting battery applications. Other microcontrollers may serve performance-critical roles, where they may need to act more like a digital signal processor (DSP), with higher clock © Embedded Computing Systems speeds and power consumption.
