具有BIBO稳定的网络系统随机容错设计
Stochastic fault-tolerant design of networked systems with BIBO stability
摘要
Abstract
The problem of stochastic fault-tolerant control and controller design for networked systems with mean square Bounded Input Bounded Output(BIBO)stability are investigated. Considering the random phenomenon of sensor failure and actuator failure, the random sensor failure and actuator failure are modeled as independent Bernoulli random variable sequence. Combined with linear matrix inequality technology and Lyapunov stability theory, by decomposing the feedback gain matrix, the mean square BIBO stability conditions under the system existence of sensor failure and actuator failure are obtained respectively. Based on the stability conditions, random fault-tolerant controller design of the system is given. Finally, the simulation example is given to demonstrate the effectiveness of design method.关键词
