This note deals with the problem of stabilization/stability for neutral systems with nonlinear perturbations. A new stabilization/stability scheme is presented. Using improved Lyapunov functionals, less conservative stabilization/stability conditions are derived for such systems based on linear matrix inequalities (LMI). Numerical examples are provided to show that the proposed results significantly improve the allowed upper bounds of the delay size over some existing ones in the literature. 相似文献

基于T-S模糊模型的非线性网络化控制系统H∞鲁棒容错控制 总被引:8,自引:0,他引:8
针对一类具有参数不确定的非线性网络化控制系统,同时考虑网络延时和丢包的影响,基于T-S模糊模型建模,通过构造Lyapunov-Krasovskii泛函,推证出了确保非线性网络化控制系统在执行器或传感器发生失效故障时具有H_∞鲁棒完整性的时滞依赖充分条件,并以求解线性或非线性矩阵不等式的方式给出了控制器的设计方法.最后,仿真算例验证了所提方法的可行性和有效性. 相似文献
