摘要

This paper tackles important problems in stable discretization of commensurate fractional-order continuous-time LTI SISO systems based on the Grunwald-Letnikov (GL) difference. New, analytical stability/instability conditions are given for the GL-discretized systems governed by fractional-order transfer functions. A stability preservation analysis is also performed for a class of finite GL approximators.
