On The Fractional Systems' Fault Detection: Evaluation of Fractional Residual

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 or...

Description
Summary: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.
