摘　　要：讨论了离散奇异摄动系统的正实控制问题。针对快速采样模型,通过线性矩阵不等式(LMI)方法,给出了系统正实性的充要条件,同时得到了奇异摄动系统的摄动参数的上界。该方法避免了传统的奇异摄动快慢分解方法,而且适用于慢速采样模型。数值算例证明了该方法的有效性。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.
