摘　　要：针对广义区间系统基于观测器的鲁棒D稳定控制问题,证明了当系统参数在某一确定的区间变化时,该控制器能保证闭环系统的正则性、因果性和D稳定性.利用线性矩阵不等式(LMI)的解,给出了控制器的设计方法.数值仿真也验证了该方法的有效性。Aimed at the D stability control of generalized interval systems in terms of the observer robustness, it was proved that the controller can guarantee the regularity, causality and D stability of the closed-loop system when the system parameters are assumed to change in a certain interval. The design scheme of the desired controller was given by using the solution to the linear matrix inequalities （LMI）. The numberical simulation results verify the effectiveness of the method.
