Design of Fractional-order Filters From The Fractional Chebyshev
Polynomials: A Meta-Heuristic Approach
Abstract
The study presents a straightforward and systematic method for creating
a low-pass filter with fractional-order Chebyshev polynomials. The
method utilize the flower pollination algorithm (FPA) as a
meta-heuristic optimization technique to calculate the optimal filter
coefficients. A stability test is conducted during the optimization
process to ensure that the filter remains stable. To validate the
method’s effectiveness, the researchers implemented the Valsa
approximation of the fractional order capacitor and conducted circuit
simulations using LTspice. The results indicated that the proposed
filter design method was successful in achieving the desired magnitude
response curve.
