【摘要】：针对一类具有积分二次约束属性的时滞网络控制系统,研究了系统在不等间隔采样下的H_∞容错控制.首先,分析并处理了网络控制系统中时滞与不等间隔采样之间的关系.以此为基础,建立了不等间隔采样下的不确定时滞网络控制系统的切换模型.通过构造Lyapunov函数,运用H_∞控制方法,以及设计具有积分二次约束属性的控制器,获得了基于LMI描述的系统时滞依赖稳定性判据.然后,建立了网络控制系统的传感器故障模型和传感器故障下的网络控制系统数学模型.通过把结论运用到传感器出现故障的网络控制系统,得到了系统在H_∞容错控制下的稳定性判据.最后,通过与其他文献介绍的方法进行比较的一个例子,说明了该方法的有效性.
[Abstract]:For a class of time-delay network control systems with integral two constraint attributes, the H_ infinity fault-tolerant control system under unequal interval sampling is studied. First, the relationship between time delay and unequal interval sampling is analyzed and processed in the network control system. Based on this, an uncertain time delay network control system under unequal interval sampling is established. By constructing the Lyapunov function, using the H_ infinity control method and designing the controller with the integral two constraint attributes, the time-delay dependence stability criterion based on the LMI description is obtained. Then, the sensor fault model of the network control system and the mathematical model of the network control system under the sensor fault are established. By applying the conclusion to the network control system of the sensor failure, the stability criterion of the system under the H_ infinity fault-tolerant control is obtained. Finally, the effectiveness of the method is illustrated by an example compared with the other methods introduced in the literature.
