摘要
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.
For a class of nonlinear networked control system（NCS） with parameter uncertainties,considering both network-induced delay and packet dropout in transmission,based on a T-S fuzzy model,and by using Lyapunov-Krasovskii functional, the delay-dependent sufficient condition of robust H_∞integrity for NCS with failures of actuator and sensor is analyzed. And the robust H_∞fault-tolerant controller gain can be obtained by solving several linear or nonlinear matrix inequalities. Finally,a simulation example illustrates the effectiveness and the feasibility of the proposed approach.
