We obtain the solution of LIFDAS. Using Gramian matrices, necessary and sufficient conditions for controllability and observability of time-varying LIFDAS are established. We acquired the criterion for time-invariant LIFDAS in the form of rank conditions. The results are more generalized than the results that are obtained for various differential-algebraic systems without impulses.eninfo:eu-repo/semantics/closedAccessControllabilityObservabilityDrazin InverseCaputo Fractional DerivativeArticle
