Robust stability check of fractional order linear time invariant systems with interval uncertainties

For uncertain fractional-order linear time invariant (FO-LTI) systems with interval coefficients described in state space form, the robust stability check problem is solved for the first time in this paper. Both the checking procedure and the Matlab code are presented with two illustrative examples. The conservatism is shown to be small. (c) 2006 Elsevier B.V. All rights reserved.
