| 摘 要： | 分析了基于卡尔曼滤波器的残差检验法对传感器缓变故障检测的不敏感性原因.针对双余度传感器缓变故障检测,采取了先故障判断后故障定位的故障检测策略,并提出了一种基于移动伪正常状态的残差构造方法.数学仿真验证了改进方法比传统方法更能够及时准确地识别双余度传感器缓变故障.

| Abstract: | The reason that the residual test method based on Kalman filter is insensitive to sensor soft fault detection is analyzed. Aiming at dual sensor fault detection, the tactic of fault orientation after fault identification is adopted, and a new kind of residual formation method, based on moving subnormal states, is proposed. Mathematical simulation results show that the improved method can identify and orientate dual sensor soft fault more exactly and quickly than the traditional method. |
