摘　　要：给出一类n阶区间系统输出反馈控制器的设计方法:首先利用适当选择的正交变换,将一类n阶区间系统的稳定性检验问题转化为较低阶的问题,并给出这类n阶区间系统稳定性判别准则,进一步地将稳定性分析结果应用于这类系统的鲁棒输出反馈控制器的设计。最后通过示例说明本文所给出的方法的有效性和实用性。In this paper, a design approach of robust output feedback stabilization for a class n-order interval systems is proposed. At first, utilizing orthogonal transformation suitably selected, the problem of investigation stability for this class of n-order interval systems can be translated into the issue of lower order interval systems. Hence, sufficient conditions of stability for this class of n-order interval systems are given. Furthermore, based on the analysis results about stability, we propose a design approach of robust output feedback , which can be used to the stabilization of this class n order interval systems. Finally, one demonstrative example is used to show the availability and the practicability of the proposed approach in this paper.
