title: Laguerre approximation of fractional systems
abstract: Systems characterised by fractional power poles can be called fractional systems. Here, Laguerre orthogonal polynomials are employed to approximate fractional systems by minimum phase, reduced order, rational transfer functions. Both the time and the frequency-domain analysis exhibit the accuracy of the approximation
