摘要
针对具有马尔可夫特性时延的网络化控制系统,基于时延准T-S模型,考虑系统参数不确定性的影响,采用状态反馈控制律,通过构造离散Lyapunov泛函,推证出了确保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充分条件,并以求解LMIs给出容错控制器的设计方法。最后通过仿真验证了文中所述方法的可行性和有效性。
A Quasi T-S fuzzy model is employed to represent the networked control system with Markov delays and parameters uncertainty. Based on state feedback control and Lyapunov-Krasovakii functional, sufficient conditions for closed-loop of networked control system possessing asymptotically stability against sensor failures are given, and the corresponding design method of robust fault-tolerant controller is presented via solving several linear matrix inequalities. Finally, simulation proved the effectiveness of the design.
