摘要
本文研究了具有变时滞的非线性随机时滞系统的时滞反馈鲁棒H∞控制问题.利用时滞分割技术,构造了新的Lyapunov-Krasovskii泛函,通过It o公式,以线性矩阵不等式(LMI)的形式给出了时滞反馈鲁棒H∞控制器存在的充分条件,通过数值仿真算例说明了结论的正确性和方法的有效性.
The H∝ control problems for nonlinear stochastic systems with time-varying delay are studied in this paper. By delay partition techniques, constructing the novel Lyapunov- Krasovskii functional, using the It5 formula, the sufficient conditions for existence of delay feedback robust H∝ controller are given in terms of linear matrix inequality(LMI). At last, the numerical example with simulation shows the correction of the results and the effectiveness of the proposed method.
