ABSTRACT
This paper derives the bounded real lemma corresponding to norm of the singular fractional-order system (SFOS). The
bounded real lemma established for both cases of
and
has no conservatism and it turns the original complex computation of
norm into linear matrix inequality (LMI) problem, which can be performed in a computationally efficient fashion. In addition, it can test the system stability automatically, which is critical for system analysis. From this advantage, the synthesis problem of
control for the SFOS is addressed in the form of LMI. The simulation study is performed to validate the effectiveness and efficiency of the proposed methods.
