- Abstract:
-
The standard bidirectional generative adversarial network (BiGAN) model structure consists of a fully connected layer and only considers the process characteristics of a single sample for statistical construction during fault detection. Therefore, an improved bidirectional generative adversarial network for industrial process fault detection is proposed. The method preprocesses the samples using a denoising autoencoder and constructs the reconstruction error as the input for the BiGAN. This approach reduces the masking of abnormal information by normal information in abnormal samples and enhances the ability of the model to detect small faults. Additionally, a long short-term codec is introduced into the BiGAN model, which enables the generator to focus on both the current process characteristics and the correlation between historical samples while generating false samples. This improves the ability of the model to detect time-series data. The proposed fault detection method was applied to the Tennessee Eastman process and an actual coal mill industrial process. This method improved the alarm rate while maintaining a low false alarm rate, which demonstrates good generalization performance.
