The weak features of the new fault are either aliased with the existing fault features and ignored, or directly covered by irrelevant interference components. To achieve separation and extraction of compound faults, multidimensional fast nonlinear blind deconvolution network (MFNBD-net) is proposed. Firstly, fast nonlinear blind deconvolution (FNBD) is extended to MFNBD based on the principle of multi-dimensional blind deconvolution to obtain the potential of decoupling composite features. Then, uniform multidimensional initialization for indicating the convergence direction is introduced to enhance the performance of multi-feature extraction. Next, based on the uniformity of harmonic distribution, trimmed envelope spectrum kurtosis for guiding the elimination of irrelevant and repetitive components in multi-dimensional output is proposed. Finally, adaptive nonlinear transformation and filter waveform penalty are incorporated into the deconvolution process and MFNBD-net is proposed. Simulation and experiments show that MFNBD-net has advantages in multi-dimensional feature decoupling and robustness, and it is a promising composite feature extraction tool.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145246005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this problem, an enhanced model-free and finite-time control framework incorporating a disturbance observer and sliding-mode control is put forward. Firstly, a second-order adaptive disturbance observer is constructed using tracking error. It is capable of responding in real-time to the system's tracking dynamics and adaptively estimating the lump disturbance, achieving collaborative improvement in estimation and tracking performance. This observer offers advantages a simple structure, few parameters, and wide applicability. Secondly, based on an established auxiliary strategy, a sliding-mode control law is designed using the virtual estimation state error of the proposed observer. This design simplifies the controller structure, ensures global sliding-mode robustness, and avoids sliding-mode chattering and high-frequency switching of the controller. Thirdly, a model-free and finite-time controller is developed by incorporating the lumped disturbance (estimated by the designed second-order adaptive disturbance observer) into the proposed sliding-mode control law through compensation, and its finite-time exponential convergence is theoretically proven. Finally, the effectiveness and superiority of the proposed method are verified through comparative experiments.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145260038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, CMTC experiences some performance degradation when using a fixed kernel bandwidth. Therefore, we propose the constrained maximum mixture total correntropy (CMMTC) algorithm, which leverages mixture correntropy to enhance flexibility by adjusting the proportion of different kernel bandwidths. In general, increasing kernel bandwidth typically leads to a reduction in the convergence speed of CMTC. Hence, based on a combined strategy, we innovatively introduce two adaptive versions of the CMMTC algorithm by considering a variable mixture coefficient. For the proposed CMMTC algorithm, under some reasonable assumptions, we have derived the mean convergence condition and the theoretical mean-square-deviation expression, which are also verified by simulation results. In comparison with other related algorithms, several experimental results demonstrate that the proposed algorithms can realize superior filtering performance.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145254285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Third, to address the nonlinear disturbances and malicious attacks within the system, an adaptive compensator is proposed to ensure system security. Furthermore, an observer-based event-triggered sliding mode controller is designed to ensure finite-time convergence to the predefined sliding mode surface. Fourth, based on the determined transition rates, it is proven that the sliding mode dynamics exhibit stochastic stability with a prescribed H∞ performance level in terms of linear matrix inequality method, and it is also shown that Zeno behavior is excluded.

It aims to improve the accuracy of state estimation and attack detection in CPPSs in the presence of D-LAA and noise disturbances. First, a discrete-time CPPSs model subject to D-LAA and unknown-statistics noise is constructed to capture the system dynamics under the influence of cyberattacks and disturbances. Second, a state estimation method based on an improved Kalman/H∞ co-filter is proposed, in which the multi-fading factor adaptive Kalman filter (MFAKF) is used to handle Gaussian noise with unknown-statistics, and the H∞ filter is used to enhance robustness against non-Gaussian disturbances. Finally, a detection algorithm based on cosine similarity matching is designed to identify anomalies by calculating the angular deviation between the estimated and measured states. Simulation results show that for the state ω1 in the IEEE 3-machine 6-bus system, the proposed MFAKF-HF reduces the RMSE by 75% relative to MFAKF and 62% relative to H∞ filtering, demonstrating the improved accuracy and robustness of the proposed estimation and detection scheme under both attack and noise conditions.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145254275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
