| Abstract: | This paper deals with the problem of positive real control for discrete-time singularly perturbed systems. For fast sampling models, a necessary and sufficient existence condition and the corresponding design approach are proposed via linear matrix inequality method. The upper bound of the parameter e is also given. The proposed method is also applicable to slow sam- pling singularly perturbed models. A numerical example is presented to illustrate its effectiveness. |
