摘要

This manuscript aims to fill the gap in the bounded real lemma and robust \(H_{\infty }\) H control condition for fractional-order systems with distributed delay (FOSDDs). At first, two order-dependent and delay-dependent bounded real lemmas for FOSDDs are proposed. Then, a robust \(H_{\infty }\) H control condition in form of linear matrix inequalities (LMIs) for the uncertain FOSDDs with norm-bounded uncertainties is obtained on the ground of the proposed bounded real lemmas. At last, several numerical examples are put forward to manifest the effectiveness and advantage of the obtained results.
