| 中文摘要 |
| 本文基于标称点方法, 研究了广义网络控制系统在短时变时延条件下的最优指数H∞控制问题. 为了减小网络诱导时延对系统保守性的影响, 系统首先被建模为一个具有范数有界不确定项的离散时间系统. 然后基于线性矩阵不等式技术和李雅普诺夫稳定性判据, 给出使得系统指数稳定的一般和最优H∞状态反馈控制器的存在条件和设计方法. 最后通过3个算例证明了本文工作的有效性. |
| 英文摘要 |
| In this paper, the optimal exponential H∞ control problem for singular networked control systems with short time-varying delay is studied by using the nominal point method. The system is first modeled as a discrete-time system with norm-bounded uncertainties in order to reduce the influence of network-induced delay on the system conservativeness. Then, the existence condition and the design method of a general and an optimal H∞ state feedback controller are given respectively based on the linear matrix inequality technique and the Lyapunov stability criterion. These controllers enable the system to be exponentially stable. Finally, three numerical examples are delivered to verify the validity of the work in this paper. |
