    (IEEE, 2015) Kazan, Fatih Alpaslan; Terzioğlu, Hakan; Ağaçayak, Abdullah Cem
    Microcontrollers are commonly used in the industrial applications. For that reason, it is crucial to learn microcontroller software and using a hardware which the written software is tested. In this study, a trial and development board which a dual in-line package PIC18F4550 microcontroller could be programmed and the written programs could be tested. In the training sets designed up to now, the connection between the microcontroller and the peripherals was fixedly executed on a copper plaque. For example, the fixed connections of LCD, graphic LCD, touch panel, analog data reading or display are provided through definite pins of microcontroller. Thus, the flexibility disappears while writing the program due to those fixed connections. In such an approach, moreover, the necessary changes may be forgotten in case related peripherals are connected to different pins. Flexibility was provided in the connections between all the peripherals and the microcontroller in the designed training set. The set includes a group of buttons, the LED group, LCD screen, graphic LCD, 7 segment displays, a keypad, an analog input, an external EEPROM, a step motor, buzzer, a real-time clock, temperature sensor, the USB and the communications unit. In any of all the aforementioned components, there is no connection which inhibits the programmer. All the industrial applications will be executed without any limitations of designing through using this experiment set.

    (IEEE, 2015) Terzioglu, Hakan; Kazan, Fatih Alpaslan; Selek, Murat
    Nowadays, reasons such as the gradual decrease of natural gas, coal, oil and oil derivatives, fluctuations in water levels in dams, and doubts surrounding the reliability of nuclear power plants and waste problems connected with them have caused people to search for renewable energy resources that have lower costs per unit, and do less damage to nature. To this end, intensive efforts have been made in the past decade to make use of solar energy for the purpose of producing electricity. As a result of these efforts, the use of solar panels is increasing rapidly. In parallel to this, the need for staff members who have knowledge and skills about these systems and are well-qualified is also increasing. In this study, a multi-purpose and educational solar energy set was designed in order to meet the need for well-qualified personnel in the field of solar energy education. This set was designed to be used in the education of students attending mechatronics, control automation, electric and electronic departments in institutions of vocational and technical education. This set enabled students to see the equipment used in the solar panels, serial and parallel connections of the panels and how electric energy is obtained from the panels. The control of the panels in the set was designed in such a way as to be performed using PLC, SCADA or microcontroller. In this way, it was made possible that in PLC, SCADA and microcontroller classes, controls can be implemented regarding the dual-axis movement of the panel. It was seen that using this set, students were enabled to receive better quality, more lasting and more effective education as a result of the instruction given to them.

    The Effect of Magnet Temperature on Speed, Current and Torque in PMSMs
    (IEEE, 2016) Bilgin, Osman; Kazan, Fatih Alpaslan
    In this study, the effect of magnet temperature on speed, current and torque in permanent magnet synchronous motor was investigated. First, the demagnetization curves of Neomag S 28VC class magnet related to different temperatures, which was used for MCS06C41 coded motor of Lenze Company, were approached. A mathematical expression was achieved to calculate the remanence value for any temperature using these curves and curve fitting method. Then, a simulation was made according to the field oriented vector control method in MATLAB/Simulink using real motor and driver parameters. The mathematical expression that gives the change of magnetic flux related to the temperature influence was included in the modelling. In this way, the change of the speed, current and torque for different magnet temperatures were made observable. Six simulations were made with 25 degrees C increase from 25 degrees C to 150 degrees C to observe the effect of the temperature on the motor much better. The simulation results have clearly demonstrated the effects of the increase of the magnet temperature especially on the current and torque.

    Improvement of ultrasonic sensor-based obstacle avoidance system in drones
    (Selçuk Üniversitesi, 30.06.2023) Kazan, Fatih Alpaslan; Solak, Haydar
    Although drone users have received the necessary training, the reflexes of making decisions against a sudden natural event such as wind and avoiding a nearby obstacle may not be sufficient. Therefore, whether drones fly autonomously or under user control, they must sense and act accordingly for an uninterrupted mission. In this study, a drone design and application for obstacle detection and obstacle avoidance were carried out. In the designed drone, Pixhawk was used as the flight control board, ultrasonic sensors were used to detect obstacles, and Arduino Uno was used as a microcontroller to obtain avoidance commands. The sensors used in obstacle detection and their performance are the most decisive factors in achieving the targeted goal. Because obstacle detection sensors are affected by electrical noises, the success of detecting obstacles decreases. For this reason, first of all, the integration of these sensors into the system was investigated and the drone was developed accordingly. Then, an algorithm was developed using a software filtering method both to minimize communication instabilities and to increase the clarity of detection. Finally, the ability to evade obstacles both while the drone is suspended in the air and while it is in motion has been investigated. In the experiments carried out, it was found that the drone was able to successfully avoid obstacles up to a flight speed of 3.94 m/s.

    The Irrigation System Fed from Biaxial PV Panels
    (IEEE, 2015) Terzioglu, Hakan; Kazan, Fatih Alpaslan; Sungur, Cemil
    In this study, an irrigation system which has an adaptive control system fed from the photovoltaic panels was designed and developed. The control system was designed as an electromechanical system which photovoltaic panel follows the sun on two axes, including both azimuth angle and zenith angle. In the executed system, the tracking of the sun was performed in both axes using dsPIC. Moreover, the control circuit with dsPIC processes the data obtained from the calculations of current-voltage and liquid levels. Differently from other studies in the literature, in this study, the source which feeds the irrigation system was determined according to the power obtained from the panel and PV panel was moved in two axes. The power generated by the panel is fed from battery if the power is below the determined power value and the panel is used if the power is above it. Through this developed algorithm, it was aimed to keep the tank full when the water is needed and prevent unnecessary discharge of the battery and lengthen its economic life depending on the quantity of charging-discharging of it. As a result of this study, the system was optimal activated without the requirement of any other energy except PV panel.

    Microcontroller based simulation of the very high frequency omnidirectional radio range (VOR) system in aircraft
    (Selçuk Üniversitesi, 31.12.2020) Kazan, Fatih Alpaslan
    As it is known, different navigation systems, such as Non-Directional Beacon (NDB), Automatic Direction Finder (ADF), Very High-Frequency Omnidirectional Radio Range (VOR), Instrument Landing System (ILS) and Distance Measurement Equipment (DME), are used for the aircraft to take off, travel and land safely. This study aims to motivate students, who educate in aviation electricity and electronics departments of aviation schools established to meet the needs of the aviation industry, to learning the microcontroller course better. To achieve this aim, the VOR receiver, which shows the aircraft's radial according to the VOR station from which receives its signal, has been simulated. Since the microcontroller to be used in simulation and the compiler to be used in programming the microcontroller may vary, only flow diagrams and basic calculations are given. In the simulations, it was seen that the phase difference between the reference and variable signals sent by the VOR station were correctly detected, and thus the aircraft could accurately determine the radial relative to the VOR station.

    A New Approach to The Installation of Solar Panels
    (IEEE, 2015) Terzioglu, Hakan; Kazan, Fatih Alpaslan; Arslan, Mustafa
    The need for electric energy, which is an indispensable part of life, is increasing with each passing day in parallel to the developments in technology. However, the fact that costs rise in meeting these needs, and that damage is done to nature while energy is being obtained bring clean energy sources such as solar and wind energies to the agenda. On the other hand, the possibility that birds, though slightly, may suffer when wind is used as a source of energy renders solar energy more environment-friendly and important. Therefore, the use of solar panels is increasing rapidly. Solar panels, which, with their increased power capacity, are used in homes, country cottages, street lighting, meeting the electricity needs of public buildings, garden lighting and irrigation systems, are especially used in meeting the energy needs in specific remote locations. In this study, a new approach was suggested in the selection of material to be used in solar panel systems in country cottages. In the suggested approach, the panels are connected in two different groups taking into consideration the hours of usage of the loads that will consume the electricity. One of these groups is used to meet instant needs whereas the other is used to charge the battery. In this way, fewer solar panels are needed compared with the conventional calculation method. Moreover, the number of batteries needed by the system is also reduced. As a result, the number of solar panels and battery-related costs can be reduced. The proposed system was tried in a country cottage in the province of Konya in Turkey in the months of July and August and it was seen that the system was able to meet its energy need from photovoltaic panels and batteries without the network.

    The Use of dsPIC in the Identification of Inertia Moment and Friction Coefficient of PMS and DC Motors
    (TRANS TECH PUBLICATIONS LTD, 2014) Terzioglu, Hakan; Kazan, Fatih Alpaslan; Selek, Murat
    In the present study, the inertia moment and friction coefficient of direct current (DC) and permanent magnet synchronous (PMS) motors were calculated. Retardation experiment was carried out to calculate these values, and current, voltage and rotation values of the motor were calculated with the help of sensors. The measurement results were read with the help of a card designed using dsPIC30F4013, a high-performance digital signal controller. Power and torque values were calculated using the data transferred into the computer. Graphs showing power-velocity and velocity-time were drawn through the use of the values that were measured and calculated. Power-time graph was obtained by using these two graphs. To be able to carry out numerical procedures using the power-time graph created, curve fitting method in MATLAB was used, and mathematical expression of the graph was obtained. The kinetic energy stored in the motor was calculated using the mathematical expression mentioned, and the inertia moment was found using this value. The friction coefficient was calculated using the torque equation for stationary running of the motor at rated speed. The results of the simulation carried out in MATLAB by using the calculated coefficients and those of the experiment were compared.
