  • A New Method for Direct Power Control of DFIG-based Wind Turbines under Voltage Disturbances 

    Olamaei, Javad؛ Mirzaeian, Mohammad (Islamic Azad University, South Tehran Branch, 2018-12-01)
    Doubly-fed induction generator (DFIG) is too sensitive to the terminal voltage reduction. Thus, it is essential to choose an appropriate controller for converters in order to have stable voltage as well. In this article, ...

  • Using Mean Shift for Iranian License Plate Detection 

    Zandian, Mohtaram؛ Ghofrani, Sedigheh (Islamic Azad University, South Tehran Branch, 2018-12-01)
    In this paper, Mean Shift (MS) as a clustering algorithm is used to localize the Iranian license plate. In this procedure after clustering, based on the optimized MS method, we applied the geometrical features and edge ...

  • A Linear Discriminant Analysis based Modulation Recognition Method for Linear Modulations 

    Ahvaraki, Mohamad Reza؛ Ghroashi, Seyed Ali؛ Mahboobi, Behrad (Islamic Azad University, South Tehran Branch, 2018-12-01)
    In this paper, a new method for signal modulation classification based on Linear Discriminant Analysis for multi-class cases is introduced and its results are compared with two other methods of automatic modulation ...

  • A NOVEL PM SHAPE for Reducing Cogging Torque in AFPMSM 

    Farnaghizad, Hamed؛ Lesani, Hamid (Islamic Azad University, South Tehran Branch, 2018-12-01)
    Torque ripple in electrical machines is an important issue which may cause several problems in use. In permanent magnet machines and machines with DC excitation, main part of torque ripple is because of cogging torque. ...
