    (International Organization on 'Technical and Physical Problems of Engineering', 2020) Ciba, S.; İskender, İres; Iskender, I.; Ariani, H.A.; 133746; Elektrik-Elektronik Mühendisliği; 06.03. Elektrik-Elektronik Mühendisliği; 06. Mühendislik Fakültesi; 01. Çankaya Üniversitesi
    Brushless DC motors are powered by a DC electric source and are used widely used in appliance, automotive, aerospace, medical and industrial equipment due to their compact size and light weight. Parallel to improvements in semiconductor industries the operating frequency of semiconductor switches and microcontrollers are getting improve and this provides conditions to use different algorithms in motor control. In this study the reference model adaptive control of a DC brushless motor will be studied. Brushless DC motors have some advantages such as long working life, high efficiency, and low maintenance requirements; however their control is a bit complicated. For this reason, there have been published many studies in relative with speed control of brushless DC motors. Classical or modern control methods can be used for this purpose. In this study, BLDC motor is controlled with firstly classical PID controller and secondly model reference adaptive control (MRAC) based on MIT law method and the results are compared. © 2020, International Organization on 'Technical and Physical Problems of Engineering'.

    Firçasiz Doǧru Akim Motorlarinin Model Referans Adaptif Kontrol Yöntemi - Mıt Kurali ile Kontrol Edilmesi
    (Institute of Electrical and Electronics Engineers Inc., 2019) Iskender, I.; Ciba, S.; 133746; 06.03. Elektrik-Elektronik Mühendisliği; 06. Mühendislik Fakültesi; 01. Çankaya Üniversitesi
    In this study, the control of Brushless DC Motors (BLDC), which gained popularity in recent years, is discussed. As a result of insufficient classical control methods, modern control methods have been needed and BLDC is controlled with model reference adaptive control (MRAC) - with MIT law method. For this purpose pulse function, sine wave and step function were applied as a reference speed and the output speed of the system was observed. Simulation results show that the speed of the system follows the speed of the reference model. Then it was thought that in the course of time the resistance value will change because of heated motor and according to this situation the resistance value increased and the output of the system is observed again. © 2018 IEEE.
