摘要

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。%Abstratc:In this paper , the problem of H•controller design for singular networked control systems with delay and data packet drpo out 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.TheH•controller design takes into considerta ion factors such as networ-induced delay, data packet dropout, external disturbance, structural insta-bility of singular systems, and impul se behavior in the network control mode.In addition, the condition for the exist-ence 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 prse etn ed design method is effective and ef asible.
