Robust Stability and Stabilization of Interval Uncertain Descriptor Fractional-Order Systems with the Fractional-Order α: The 1≤α<2 Case

الملخص EN

Stability and stabilization of fractional-order interval system is investigated.

By adding parameters to linear matrix inequalities, necessary and sufficient conditions for stability and stabilization of the system are obtained.

The results on stability check for uncertain FO-LTI systems with interval coefficients of dimension n only need to solve one 4n-by-4n LMI.

Numerical examples are presented to shown the effectiveness of our results.
