Robust H_∞ Control for Uncertain Discrete Time-delay Systems with Controller Gain Variations

利用线性矩阵不等式(LMI)方法,讨论有记忆控制器增益变化的不确定离散时滞系统的鲁棒H∞控制问题.控制器存在的条件由线性矩阵不等式的形式给出,并给出相应的H∞控制器的设计方法.

The problem of robust H∞ control is discussed for the uncertain discrete time-delay systems with controller gain variations. By using of the linear matrix inequality （LMI）, the condition for the existence of an H∞ state-feedback controller is derived and the design method is also given.
