摘要
针对基于Kalman滤波器的残差检验法对传感器缓变故障检测的不敏感性,提出一种基于移动伪正常状态的残差检验法.数学仿真验证了基于移动伪正常状态的残差检验法能够及时准确地识别传感器缓变故障.
The residual test method, a common fault detection method for sensors, is insensitive to soft fault detection. For the sake of identifying soft faults effectively, a new residual test method based on moving subnormal states is proposed in this paper. And its validity is testified by mathematical simulation results, as shown in figures 1 through 4.
