Recursive Identification for Fractional Order Hammerstein Model Based on ADELS

Algorithm 2

Identification process of the fractional Hammerstein model.

(1)	Collect the input/output data {};
(2)	Obtain the initial of unknown parameters by using Algorithm 1;
(3)	While (t < max number of iterations N)
(4)	Estimate the value of system coefficient according to the equation (31);
(5)	Update the fractional order according to the equation (38);
(6)	If the criterion function value satisfies the error accuracy
(7)	Break;
(8)	End;
(9)	t = t + 1;
(10)	End while;
(11)	Postprocess results and visualization.
