中文摘要
      对抗自编码器(AAE)模型训练时, 样本与特征表示间的互信息衰减现象, 不仅影响模型的故障检测性能, 而 且难以直接用于故障估计. 为此, 本文设计了一种基于逐层扩展互信息对抗自编码器的故障检测策略, 通过合并隐 层特征与原始数据, 显性引入特征空间与每层神经网络的互信息, 实现了信息的高效整合及特征与输入样本间的最 大化相关性; 并在此基础上, 开发了一种梯度下降反馈算法, 设计了基于深度学习的故障估计策略, 有效避免了故障 估计的复杂机理建模与大规模系统参数辨识; 最后, 通过连续搅拌釜式加热器验证了所提方法的有效性和优越性.
英文摘要
      The mutual information decay between samples and feature representations during the training of the adversarial autoencoder (AAE) model not only affects the fault detection performance, but also makes it difficult to be used directly for fault estimation. To this end, this paper designs a fault detection strategy based on extended layer-by-layer mutual information adversarial autoencoder (ELM-AAE), which achieves efficient integration of information and maximized correlation between features and input samples by merging the hidden layer features with the original data and explicitly introducing mutual information between the feature space and each layer of the neural network. A gradient descent feedback algorithm is then developed to construct a fault estimation model based on deep learning, which effectively avoids the complex mechanism modeling and large-scale system parameter identification for fault estimation. Finally, the validity and superiority of the proposed method was verified by continuous stirring tank heater (CSTH).
