Design of Fractional Order Digital Differentiators and Integrators Using Indirect Discretization
Mathematics Subject Classification: 26A33, 93B51, 93C95 In this paper, design of fractional order digital differentiators and integrators using indirect discretization is presented. The proposed approach is based on using continued fraction expansion to find the rational approximation of the fractional order operator, s^α. The rational approximation thus obtained is discretized by using s to z transforms. The proposed approach is tested for differentiators and integrators of orders 1/4...
