摘　　要：针对一类具有参数不确定的非线性网络化控制系统,基于T-S模糊模型建模,推证出了确保非线性网络化控制系统在传感器发生失效故障时具有鲁棒完整性的时滞依赖充分条件,并以求解矩阵不等式给出了容错控制器的设计方法。最后以一个仿真算例验证了文中所述方法的可行性和有效性。The problem of robust fault - tolerant control for a class of nonlinear networked control systems （NCSs） with parameter uncertainties is investigated in this paper. A T - S fuzzy model is employed to represent the nonlinear controlled plant in the NCSs. The less conservative integrity design for NCSs with failures of actuator and sensor is analyzed based on a delay - dependent approach, and the robust fault -tolerant controller gain can be obtained via solving several linear matrix inequalities （LMIs）. Finally, an example is used to illustrate the effectiveness and the feasibility of the approach proposed.
