基于观测器的网络切换模糊系统的反馈控制

Feedback Control Based on Observer in Network Switching Fuzzy Control System

针对一类系统状态不可测的网络切换模糊系统,研究了在单包传输且没有丢包情况下的稳定控制问题。使用切换技术、T-S模糊模型及Lyapunov函数方法,设计模糊观测器及切换律,以矩阵不等式的形式给出使系统渐近稳定的条件。最后仿真结果表明方法的有效性。

For a class of the network switching fuzzy systems whose states were unmeasurable, the stability control problem was investigated under the condition of single-packet and no lost packet. Using switching technology, T-S fuzzy model and Lyapunov function, the fuzzy observer and switching law were designed. When the matrix inequality form existed, the conditions which made the system asymptotically stable were provided. Finally the simulation results expatiated the effectiveness of the proposed method.
