| 摘 要： | 建立了同时具有前向通道传输时延和反馈通道传输时延的线性分布式网络控制系统的数学模型.用该数学模型将系统变换为具有状态与控制时变时滞的线性时滞系统.基于代数Riccati方程方法,提出了H∞鲁棒输出反馈控制方法,以使系统闭环控制稳定.仿真算例结果表明,在t=2.5 s时,系统状态都达到了0,保证了系统具有较快的零状态响应速度.给出了这类系统的H∞鲁棒输出反馈控制器的综合设计示例.

| Abstract: | A mathematical model was proposed for a linear distributed network control system with delays in forward and feedback channels, and it was used to transform the system into a linear system with time-varying delays in state and control input. A robust H-infinity control scheme of output feedback based on an algebraic Riccati equation was presented to stabilize the closed loop system. Results of a simulation example show that the state of the system reaches 0 at t = 2.5 s, indicating a quick response to zero state. As an example, a design of a robust H-infinity controller for output feedback was presented. |
