Fractional Order Butterworth Filter

Mehmet Emir Koksal

Butterworth filter, control system, fractional order.

Fractional order Butterworth filter derived from the conventional 3rdorder Butterworth filter by the transition of the ordinary derivativeto the fractional one as in is investigated in this paper. The change of the filter characteristics is studied depending on the order of the fractional derivative. Effects of the transformation on the components’ behaviors of the filter is formulated. Design of the filter in the sense of choosing the filter parameters to satisfying the given specifications is described.
