| 中文摘要 |
| 部件（如传感器或执行器）的实效将导致系统性能的下降甚至完全实效。因此，在设计容错控制系统时确定部件重要度是非常重要的。本文提出了部件静态和动态重要度，它们分别表示了部件实效对系统静态和动态性能的影响程度。借助仿真和矩阵转换的运算，本文提出了能同时计算m个部件静态和动态重要度的CAD算法，例子验证了该法的有效性。 |
| 英文摘要 |
| Failure of component, such as a sensor or an actuator, may results in deterioration of properties or even complete failure of a control system. Therefore, it is very important to determine the degree of importance of a component in the design process of a fault-tolerant control system. In this paper, both degrees of static and dynamic importance of a component are presented, which denote the changed amplitude of static and dynamic properties respectively when a step change occurs in the out-put of a component. After simulation of control system and computation of transfer matrix, a CAD algorithm is presented, which can simultaneously compute degree of static and dynamic importance of a components. An example showing computation of degrees of importance in a process control system is studied, and the theoretical results are vertified by experiment. |
