中文摘要：
保证费用的问题为与包退学学生和传播延期一起的联网的控制系统(NCS ) 的活跃差错容忍的控制器(AFTC ) 设计在这份报纸被学习。就包退学学生和传播延期而言，一个 piecewise 常数控制器被采用。与一个保证费用函数，其数字等于致动器的数字的最佳的控制器被设计，并且设计进程作为能被存在软件解决的一个凸的最佳的问题被提出。控制策略如下被建议：当致动器失败出现时，差错察觉和隔离单位发送信息到与最小的保证费用价值选择策略，然后最佳的稳定控制器的控制器被选择。二个解说性的例子被给表明建议途径的有效性。由与存在方法作比较，我们的方法有更好的表演，这能被看见。
英文摘要：
The problem of guaranteed cost active fault-tolerant controller （AFTC） design for networked control systems （NCSs） with both packet dropout and transmission delay is studied in this paper. Considering the packet dropout and transmission delay, a piecewise constant controller is adopted. With a guaranteed cost function, optimal controllers whose number is equal to the number of actuators are designed, and the design process is formulated as a convex optimal problem that can be solved by existing software. The control strategy is proposed as follows： when actuator failures appear, the fault detection and isolation unit sends out the information to the controller choosing strategy, and then the optimal stabilizing controller with the smallest guaranteed cost value is chosen. Two illustrative examples are given to demonstrate the effectiveness of the proposed approach. By comparing with the existing methods, it can be seen that our method has a better performance.
