摘　　要：研究了广义区间系统的静态输出反馈鲁棒无源控制问题.首先给出广义区间系统的等价描述;然后利用用线性矩阵不等式,给出自治系统广义二次稳定且无源的充分条件;随后给出了静态输出反馈鲁棒无源控制器的存在条件,并利用线性矩阵不等式的解构造了相应的控制器;最后数值例子说明了该结论的有效性.The problem of static output feedback robust passive control for a class of generalized interval systems is discussed . Firstly, a kind of equivalent description of the generalized interval systems is given. Then, using the method of linear matrix inequality （LMI）, a sufficient condition is presented for the autonomous system being generalized quadratically stable and passive. Furthermore, the existence condition of a static output feedback robust passive controller is given and the explicit expression of the controller is derived in terms of the solution of LMIs. o. Finally, a numerical example is given to demonstrate the feasibility of the conclusion.
