| 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-Krasovskii泛函,推证出确保网络化控制系统在执行器或传感器发生失效故障时具有鲁棒完整性的充分条件,通过求解LMIs给出容错控制器的设计方法.通过仿真实例得到,网络化控制系统在发生执行器失效故障时仍是渐近稳定的,说明该方法对于具有马尔可夫特性时延的影响,不确定网络控制系统在执行器失效故障时具有鲁棒完整性.

| Abstract: | Aimed at the networked control system with Markov delays and based on a quasi T-S fuzzy model, and taking the parameter's uncertainty into consideration as well,a sufficient condition for the networked control system to have robust integrity when the actuator or transducer failed in operation was derived by constructing a discrete Lyapunov-Krasovakii functional.A design method of fault-tolerant controller was given by solving LMIs,also.It was verified by system simulation that the networked control system w... |
