Output Feedback Decentralized Robust H_∞ Control for Nonlinear Uncertain Interconnected Systems with Time-varying Delays

针对一类系统状态和关联项均含有时变时滞以及系统具有非线性扰动的不确定关联系统,研究其输出反馈分散鲁棒H∞控制问题。应用线性矩阵不等式的方法,给出系统通过输出反馈分散鲁棒控制达到渐近稳定且具有H∞性能的充分条件。最后通过仿真实验证明所得结果的有效性。

The problem of output feedback decentralized robus H∞ tcontrol is investigated for nonlinear uncertain interconnected systems with time-varying delays and nonlimear disturbance. By using linear matrix inequality （LMIs）, sufficient conditions for existence of output feedback decentralized robust H∞ stabilization are presented. An illustrative example and simulation results are given to demonstrate the effectiveness of the proposed design methods.
