| 摘 要： | 针对一类具有时变时延和丢包的网络化控制系统,同时考虑模型参数不确定性和外界扰动的影响,基于一种状态多时延模型,以时滞依赖的方法,推证出了确保闭环系统在执行器或传感器发生失效故障时具有鲁棒H∞完整性的判据,并以求解线性或非线性矩阵不等式的方式,给出了鲁棒H∞容错控制器的设计方法。由于模型中考虑了时延下界,且证明过程未进行模型转换和交叉项放大处理,其结果具有较少保守性。最后以一仿真示例验证了所述方法的有效性。

| Abstract: | The problem of robust guaranteed cost fault-tolerant control for a class of networked control system with time-varying delay and packet dropout was investigated.Both parameter uncertainties and external disturbance were addressed.Based on the model with multiple successive delays in the state,a stability criterion for the closed-loop system with robust integrity against actuator or sensor failures was given in terms of the time-delay-dependent approach.Then a method of the robust fault-tolerant controller d... |
