Abstract :
The stability bound problem of linear time-invariant singularly perturbed systems is considered. A set of new stability conditions based on the frequency-domain representation is derived. The stability criteria can be easily verified by computing certain singular values within finite frequency intervals. Illustrative examples show that the proposed criteria actually induce a less conservative ε bound than the existing criteria, and for certain cases an infinite ε bound may be obtained
