| 摘 要： | 研究具有数据丢失的网络化控制系统的基于观测器的镇定问题。受控对象是由T-S模糊模型描述的非线性时滞系统。把数据丢失过程建模成独立同分布过程。利用模糊Lyapunov函数方法得到了闭环系统随机稳定的充分条件,其基于观测器的反馈控制器可通过求解一组线性矩阵不等式来设计。一个仿真例子说明方法的有效性。

| Abstract: | This paper deals with the problem of observer-based stabilization of networked control systems(NCSs) with transmitted data dropout.In the NCS under consideration,the plant is a time-delay nonlinear system that is represented by a Takagi-Sugeno(T-S) time-delay fuzzy system.The dropout process is modeled as an identically independently distributed process.Based on a fuzzy Lyapunov function method,a sufficient condition for the solvability of the problem is given.The observer and controller are constructed by solving a set of LMIs.A simulation example is provided to demonstrate the effectiveness of the proposed methods. |
