In this paper, decentralized robust H∞ output feedback control problem for large-scale interconnected system with value bounded uncertainties in the state, control
input and interconnection matrices is investigated. A new bounded real lemma for the large-scale interconnected systems is
derived by Lyapunov stability theory and linear matrix inequality method. Based on the new bounded real lemma, a sufficient
condition expressed as matrix inequalities for the existence of a decentralized robust H∞ output feedback controller is obtained. The controller which enables the closed-loop large-scale system robust stable and
satisfies the given H∞ performance is designed through a homotopy iterative method. Finally, a numerical example is given to illustrate the effectiveness
of the proposed method. 相似文献

Decentralized H-infinity state feedback control for discrete-time singular large-scale systems 总被引:1,自引:0,他引:1
The decentralized H-infinity control problem for discrete-time singular large-scale systems is considered. Based on the bounded real lemma of discrete-time singular systems, a sufficient condition for the existence of decentralized H-infinity controller for discrete-time singular large-scale systems is presented in terms of the solvability to a certain system of linear matrix inequalities by linear matrix inequality (LMI) approach, and the feasible solutions to the system of LMIs provide a parameterized representation of a set of decentralized H-infinity controller. The given example shows the application of the method. 相似文献

针对一类范数有界参数不确定性的广义离散线性系统,研究了该系统的状态反馈鲁棒H∞控制问题.利用线性矩阵不等式(LMI)的方法,得到了问题可解的条件,并给出了相应的状态反馈控制律.在一定条件下,所得的状态反馈鲁棒H∞控制律使广义离散线性系统对所有容许的不确定性参数,能够保证闭环系统正则、具有因果关系并且渐进稳定,同时其传递函数矩阵能够满足给定的H∞性能指标.正常离散线性系统的相对应结果可作为论文结果的特殊形式.仿真例子验证了该方法的正确性. 相似文献
