Asma Aribi, Mohamed Aoun, Slaheddine Najar, Mohamed Naceur Abdelkrim . On The Fractional Systems Fault Detection: Evaluation of Fractional Residual. International Journal of Computer Applications. 45, 17 ( May 2012), 37-43. DOI=10.5120/7005-9574
The paper deals with fractional residual evaluation. Three methods to evaluate fractional residuals generated by dynamic parity space method are presented. They are based on the fractional derivative approximations: the Grunwald, the pole-zero and the Diethelm approximations. They are compared in order to select the best method in terms of precision and minimum detection time delay. The selected method is used to evaluate residual of a real system.
