(Gazi Universitesi, 2019) Kivanc,O.C.; Ustun,O.; Tosun,G.; Oguz,E.; Mutlu,Y.
Fluid control is one of the essential automation application area in industry. In order to fluid control effectively and precisely, valves which are crucial components, need a controlled rotating motion which leads to implement electric motors, electronic controller and gear systems altogether. In this study, an electric motor actuated valve system is designed and prototyped. The design phases are including switch mode power supply (SMPS) design, motor controller circuit design, mechanical implementation and controller design. The designed valve system is manufactured and tested using multi-disciplinary fashion. The application problems are solved by using the proper control techniques and strategies. The precise position control of butterfly disc is also achieved. According to the related industrial standard and application requirements, the experimental results show the effectiveness of the design approach. © 2019, Gazi University Eti Mahallesi.

Design and manufacture of electric powertrain and its cooling system for ITU EV project
(Institute of Electrical and Electronics Engineers Inc., 2014) Ustun,O.; Cakan,M.; Tuncay,R.N.; Mokukcu,M.S.; Kivanc,O.C.; Mutlu,Y.; Tosun,G.
In recent years all expositions of cars show that every car manufacturing company is developing at least one electric vehicle. Recently, ITU ALEK (Istanbul Technical University Alternative Energy Club) members and its supervisor created an electric vehicle project called ITU EV (electric vehicle). This project is about developing a drive system for a conventional internal combustion engine (ICE) vehicle. The project which started in 2011, has four different main research areas. These are electric powertrain which includes water cooling design, battery part, controlling part, mechanical construction and outer design part. In this study, electric powertrain design, cooling calculations and design, and production parts of the project will be investigated. For electric drivetrain a special design of 70 kW BLDC (brushless dc) motor is produced and laboratory tests are made. The rated voltage is chosen as 355 V. © 2014 IEEE.

Design of a position controlled electric actuator used in fluid control valves
(Institute of Electrical and Electronics Engineers Inc., 2016) Tosun,G.; Kivanc,O.C.; Oguz,E.; Mutlu,Y.; Ustun,O.
Valves are the main elements for controlling fluids in industry and other application areas. To control flow precisely, valves need a controlled action which leads to implement actuators, gear systems and electronic controllers. Increasing dominance of electrical actuators due to the advantages of easy control and intervention and space-efficient designs brings seldom implementation of hydraulic and pneumatic actuation. In fluid control applications, the main target is to obtain the right position, i.e. angle for rotary actuators, for adjusting flow rate. In this study, the design and implementation of a position controlled electrically actuated valve used for fluid control are presented. The design phases of system universal power supply and electronic control system are given and the experimental results of position control which are representing the validation the design study is also discussed. Also a special current control scheme is used to overcome transient disruptions. © 2016 IEEE.
