英文摘要：

In this paper, the uniformity issue of the small parameter on linear time-invariant singularly perturbed systems is addressed, and stability and stabiliz- ability are studied. A new field of viewing a singularly perturbed system （SPS） as a parameterized system is considered, when the interval of the parameter is within a bound but not closed interval. The dependence of the system on c is discussed for this parameterized system whereby the system orders are reduced as e --~ 0. The linear matrix inequality method is used to show the stability and stabilizability of the two time scale control system. The sufficient condition for the parameterized system to be uniformly stable and uniformly stabilizable has been obtained.
