非线性广义系统时滞相关的模糊控制

Delay-Dependent Fuzzy Control for Nonlinear Descriptor Systems

研究T-S模糊广义时滞系统的时滞相关稳定性问题．通过定义新的Lyapunov函数,给出时滞相关稳定性判据．进一步考虑模糊权重的作用,将不同子系统间的相互影响考虑到一个矩阵中,给出放宽的模糊控制器设计方案．数值算例表明所得结论较已有文献具有较小的保守性．

The delay-dependent stability condition of T-S fuzzy descriptor systems with time-varying delay is discussed. A delay-dependent stability criterion is proposed by defining a new Lyapunov function. With the effective application of weights, a less conservative fuzzy controller design method is given. The relaxed design method includes the interactions of different subsystems into one matrix. At last, some examples are given to illustrate that the new sufficient condition is less conservative than the results given by previous literature.
