Researchers have developed a new method for detecting control valve stiction in industrial processes by combining optimal transport imaging with deep covariance alignment (Deep CORAL). This approach converts control loop signals into 2D images that capture dynamic behavior. A convolutional neural network is trained to learn domain-invariant features by optimizing both a cross-entropy loss on simulated data and a Deep CORAL loss on unlabeled industrial data, effectively mitigating domain shift. The methodology demonstrated high accuracy, diagnosing 18 out of 20 industrial loops with 100% recall for stiction cases. AI
