不确定时延网络控制系统的稳定性设计
Stability design for networked control system with uncertain time delay
摘要
Abstract
Since the control systems have characteristics of network time⁃delay and uncertainty in the network environment, a common mode feedback controller without assigning specify parameters in advance is used to establish the closed⁃loop network control system model with the state feedback by taking into account of fact that the lower bound of the maximum allowable net⁃work induced delay is not zero and the system has uncertainty characteristics. The quadratic integral item in Lyapunov⁃Krsaso⁃vskii functional is defined directly by introducing the integral inequality approach,which can avoid the conservative property caused by model transformation of the system and definition of the cross terms. On this basis,the condition that makes the net⁃worked control system robust stability is derived. The state response curve of the system is obtained by conducting Matlab simulation for the model. The system state tends to be stable,which shows the validity and feasibility of the conclusion.关键词
