- The optimal input signal design is a technique of generating an informative excitation signal to estimate the model parameters with maximum accuracy. In the paper, a novel optimal input formulation and a numerical scheme for fractional-order LTI system identification are presented. The Oustaloup recursive approximation (ORA) method is used to determine the fractional-order differentiation in an integer-order state-space form. Then, the proposed method is used to obtain an optimal input signal for fractional-order system parameter estimation from the interval 0.5 ≤ ≤ 2.0. The methodology presented in this paper has been verified using numerical examples, and the experiment results have been discussed.
