针对广泛存在于许多领域和行业的奇异被控系统模型,考虑网络控制环境下存在的网络诱导时延、数据包丢失、外部扰动、奇异系统结构不稳定性和脉冲行为等复杂因素,利用Lyapunov和线性矩阵不等式方法,研究了状态反馈控制方式下奇异网络控制系统H!控制器设计和优化问题,提出了奇异网络控制系统状态反馈H!控制器存在的条件、H!控制器设计及其优化方法以及相应的扰动衰减度求取方法。系统仿真实例表明了提出的设计方法有效且可行。

In this paper,the problem of H∞controller design for singular networked control systems with delay and data packet dropout is investigated. The design and optimization of the H∞controller are investigated in the status feedback control manner by utilizing Lyapunov and linear matrix inequality methods. The H∞controller design takes into consideration factors such as networ-induced delay,data packet dropout,external disturbance,structural instability of singular systems,and impulse behavior in the network control mode.In addition,the condition for the existence of the status feedback H∞controller in the singular networked control system,the design and optimization method of H∞controller and the corresponding disturbance decay rate solutions are presented. Simulation examples showed that the presented design method is effective and feasible.
