研究具有扇区有界非线性时变时延离散系统的非脆弱非线性记忆状态反馈H∞控制器的设计问题.提出一种具有更一般性的控制器增益不确定,并采用Lyapunov-Krasovskii泛函及线性矩阵不等式技术给出了控制器设计的一个时滞依赖的充分条件.最后通过一个例子验证了所提出方法的有效性. The problem of designing a non-fragile nonlinear memory state feedback H∞ controller with sector-bounded nonlinear time-varying delay discrete-time systems is studied. A more generalized controller gain uncertainty is proposed. Lyapunov-Krasovskii And the linear matrix inequalities (LMIs) give a sufficient condition for the delay-dependent controller design. Finally, an example is given to verify the effectiveness of the proposed method.
