The SBL fitting integer order approximation method calculates an integer-order approximate model in the frequency domain by matching the fractional-order derivative and its integer order approximate model to the loci kp and ki obtained in the parametric plane. Users can easily find integer order approximation models of the fractional-order derivatives using the M_SBL function.
