就一类具有状态及控制滞后的非线性不确定随机系统,研究了其鲁棒H∞控制.文中用线性矩阵不等式(LMI)的方法设计了一种状态反馈控制器,使得所得到的闭环系统鲁棒随机稳定且满足所需要的H∞性能指标.仿真算例说明了该方法的有效性.
The problem of robust H∞ control is studied for a class of nonlinear stochastic uncertain systems with delayed states and controls. A state feedback controller is designed in terms of LMI. The resulting closed-loop system is robust stochastic stable and satisfies a prescribed H∞ performance level. A numerical example is given to show the effectiveness of proposed method.
