However, existing studies require labor-intensive tasks of training domain experts and annotating semantic knowledge in a specified format. Moreover, due to the domain shift problem (DSP), models trained solely on seen faults experience a decrease in performance when transferred to unseen faults. To reduce the annotation burden and address the DSP, we propose a test-time semantic adjustment method driven by the large language models (LLMs), which focuses on annotating and optimizing semantic knowledge. Firstly, with carefully designed prompts, semantic knowledge is automatically annotated by the LLM based on unstructured professional corpora. Secondly, to overcome the DSP caused by the lack of unseen faults, this study introduces the concept of test-time adjustment for zero-shot diagnosis. Specifically, we design a dual-view semantic knowledge adjustment strategy that employs information on unseen faults from unlabeled test data to adjust the semantic knowledge. This simple yet effective strategy can also be applied to other zero-shot diagnosis methods. Last but not least, we propose the class-agnostic feature extraction to enhance the cross-category transferability of extracted features for preventing overfitting to seen faults. We conduct experiments on the Tennessee-Eastman process (TEP) and a real thermal power plant (TPP), and the proposed method achieves an average improvement of 11.34% in terms of the accuracy of unseen faults on the TEP dataset, and 6.87% on the TPP dataset.</div></div>","PeriodicalId":50615,"journal":{"name":"Control Engineering Practice","volume":"164 ","pages":"Article 106406"},"PeriodicalIF":5.4,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144194495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This feature is further leveraged to enable semi-autonomous operations, allowing a human operator to assist the robotic counterpart in completing harvesting tasks.

State-of-the-art Cartesian-based trajectory planning methods overcome limitations inherent in traditional Frenet-based approaches, particularly regarding constraint violations in high-curvature scenarios. However, these methods encounter theoretical challenges in handling reference line constraints, hindering their direct application in road scenarios. In this paper, an optimization-based trajectory planning method in Cartesian Frame is proposed to address road scenarios with multiple reference lines. The main work can be summarized into three parts. In the first part, The on-road trajectory planning task is reframed as an Optimal Control Problem (OCP) with multiple-reference lines constraints (MRLC), where the nominal OCP ensures safety and feasibility. The incorporation of nominal MRLC ensures that the generated trajectory closely follows the reference lines while maintaining the trajectory’s longitudinal deformation capability. However, nominal MRLC, which involves a minimum optimization problem when describing the distance between the trajectory and reference lines, cannot be directly embedded into an OCP. To address this issue, in the second part, an approximate calculation method is proposed to explicitly describe MRLC. The MRLC constructed in this way not only preserves the trajectory’s good deformability but also handles the generation of continuous lane-changing trajectories. In the third part, an improved dynamic programming approach tailored for multi-reference line scenarios is proposed, providing high-quality initial guesses for OCP-MRLC to enhance its convergence speed. Finally, comprehensive benchmarking against state-of-the-art methods is presented, showcasing the significance of the proposed OCP-MRLC in meeting reference line constraints and ensuring trajectory quality.
