“…Corollary 1. For a given matrix K c and constant delays h, d the 2-D singular closed-loop delayed system (13) with out parameter uncertainties is admissible with a prescribed H ∞ performance level 𝛾 > 0 if there exist symmetric positive-definite matrices P h , P v , Q h , Q v , Z h , Z v , N h , N v , appropriately dimensioned matrices M i , S, Y, W, and any symmetric matrices R h , R v , (i = 1, 2, 3), such that the following LMIs holds…”
