摘要
基于T-S模糊模型方法,研究一类非线性区间时滞系统的稳定性分析与镇定问题.基于一组线性矩阵不等式的可解性,给出了非线性时滞系统时滞相关稳定和镇定的充分条件,并通过构造新的模糊权依赖型Lyapunov泛函,降低了稳定性准则的保守性.最后通过仿真例子表明了所提方法的有效性.
Problem of delay-dependent stability analysis and stabilization for a class of nonlinear delay systems described by fuzzy T-S model is studied. Based on the feasibility solutions of some linear matrix inequalities, the delaydependent stability criteria and the stabilization design scheme are derived. A new Lyapunov function with fuzzy weighing matrices is developed, and the conservativeness of the stability criterion is decreased. Finally, numerical examples show the effectiveness of the results.
