| 摘 要： | 故障诊断是容错控制技术的基础,本文采用了一种独特的辨识算法,通过对系统开环增益的辨识而确定控制系统执行器的工作状态。仿真结果表明,该算法可以快速、有效地确定出当前执行器的工作状态。经过进一步的改进,该算法还可以应用于控制系统其他参数的故障诊断。

| Abstract: | Fault diagnosis is a base for fault-tolerant control technology.This paper adopted a particular identification method in which the open-loop gain is identified to determine current status of actuator operation in a control system.The simulation results show that the identification method can confirm the current status of actuators effectively and efficiently.By further modified,the method presented here may be applied to the fault diagnosis for other parameters in control systems. |
