    Analysis of the Band-Pass and Notch Filter with Dynamic Damping of Fractional Order Including Discrete Models
    (ETF – School of Electrical Engineering, University of Belgrade, 2018) Bošković, Marko; Šekara, Tomislav B.; Rapaić, Milan R.; Lutovac, Budimir; Daković, Miloš; Govedarica, Vidan
    The paper presents analysis of the second order band-pass and notch filter with a dynamic damping factor βd of fractional order. Factor βd is given in the form of fractional differentiator of order , i.e. βd=β/s, where β and  are adjustable parameters. The aim of the paper is to exploit an extra degree of freedom of presented filters to achieve the desired filter specifications and obtain a desired response in the frequency and time domain. Shaping of the frequency response enables achieving a better phase response compared to the integer-order counterparts which is of great concern in many applications. For the implementation purpose, the paper presents a comparison of four discretization techniques: the Osutaloup’s Recursive Algorithm (ORA+Tustin), Continued Fractional Expansion (CFE+Tustin), Interpolation of Frequency Characteristic (IFC+Tustin) and recently proposed AutoRegressive with eXogenous input (ARX)-based direct discretization method.

    Novel Band-Pass and Notch filter with Dynamic Damping of Fractional Order
    (2017) Bošković, Marko; Šekara, Tomislav B.; Rapaić, Milan R.; Lutovac, Budimir; Daković, Miloš; Govedarica, Vidan
    The paper introduces a novel the second order band-pass and notch filter with dynamic damping factor βd of fractional order. Indeed, the factor βd has a form of fractional differentiator of order α, i.e. βd=β/s α, where β and α are adjustable parameters. Shaping of the frequency response enables achieving better phase response compared to the integer-order counterparts which is of great concern in many applications. The aim of the paper is to exploit an extra degree of freedoms of presented filters to achieve the desired filter specifications and obtain desired response in the frequency and the time domain.
