| 摘 要： | 本文研究了不确定线性离散系统的线性可镇定性，即是否存在一个能镇定不确定系统的线性状态反馈。首先证明了一个离散系统的二次稳定等价于其对偶系统的二次稳定，在此基础上给出了离散系统二次可镇定的充要条件，该系统的检验可以转化为凸优化问题，最后给出了一个算例表明本文提出方法的有效性。

| Abstract: | The quadratic stabilization of uncertain discrete systems is considered (i. e.,if there exists a linear feedback control that stabilizes the uncertaiin systems) in this paper. It is shown that the quadratic stabilization of an uncertain discrete system is equivalent to that of its dual system. Necessary and sufficient conditions for quadratic stabilization are presented. Finally, a numerical example is given. |
