| 中文摘要:针对具有网络时延和执行器部分故障的网络化控制系统，考虑系统模型可能具有的参数不确定性以及未知扰动，研究执行器饱和时的稳定性问题。对网络时延提出离散事件触发机制，执行器部分故障采用故障矩阵方式，饱和项采取线性凸包法,由此推证出了闭环系统模型。构造Lyapunov 泛函，得出闭环系统在吸引域内达到稳定的充分必要条件，由此得到相应控制器的设计方法。利用仿真证明上述对系统的处理确实可以使系统达到渐近稳定，而事件触发机制也确实可以减少数据量的传输。 |

| Abstract:A network control system with network delay and actuator failure is studied. Considering the uncertainties and unknown perturbations of the system model, the stability of the actuator is studied when the actuator is saturated. A discrete event triggering mechanism is proposed for the network delay. A faulty matrix method is used to solve the fault of the actuator. The closed - loop system model is taken by linear convex method. The Lyapunov functional is constructed and the sufficient and necessary conditions for the stability of the closed-loop system in the attracting domain are obtained. The design method of the corresponding controller is obtained. The simulation results show that the above-mentioned system can achieve the asymptotic stability of the system Mechanism can also reduce the amount of data transmission. |
