摘要 利用T-S模糊模型对一类非线性连续不确定时滞系统进行建模,通过对时变时滞不确定T-S模糊系统基于状态反馈控制器二次稳定性问题的分析,给出了使系统二次稳定具有增益变化的模糊状态反馈控制器存在的充分条件,该充分条件以线性矩阵不等式的形式给出, 因其所有参数都是线性的,所以具有数值易解性。设计实例表明了该设计方法的可行性和有效性。 Based on the T-S fuzzy model, the problems of stability for a class of T-S fuzzy time-delay systems under the state feedback control gain, variation gain are discussed by means of linear matrix inequality （LMI）. A sufficient condition of stability of a class of time-delay systems via T- S fuzzy models is derived, which is expressed with linear matrix inequality. An example shows the validity of the proposed design approach.
