A ROV-based Deep-sea Mining Vehicle (RDMV), consisting of two ROVs and a mining robot (MRT), is instead of the traditional tracked Deep-sea mining vehicle. Firstly, the dynamic model of the RDMV as a control object is established based on Lagrangian function. Secondly, a cooperative control strategy is proposed for traction and sinking control of the RDMV. A distributed model predictive control (DMPC)-based controller is developed to obtain virtual speed control laws to meet the control objects. To track the virtual speed control laws, a learning-based model predictive control (LMPC)-based controller is investigated to compute the ROVs' optimal control input, where a Kinky Inference (KI) prediction function is introduced in the state transition model to estimate the unknown external disturbances under random noise. Finally, the feasibility and the superiority of the LMPC controller is preliminarily verified in a degenerate individual motion control of a ROV, and then the cooperative control strategy is proven to be effective through numerical simulations.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143588689","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, we propose a position sensorless control method that combines a global fast terminal sliding mode observer (GFTSMO) with a phase-locked loop (PLL) estimation scheme. First, the GFTSMO is introduced to reduce the significant chattering that typically occurs in traditional sliding mode observers (SMO). This control scheme can help the state variable converge to an equilibrium state from any initial condition and minimize chattering. Second, we implement a PLL estimation scheme to replace the conventional arc-tangent estimation method. This method avoids the triggering of high-frequency oscillations, thereby improving the estimation precision and robustness of the control system. In addition, we discuss the stability of the proposed GFTSMO using the Lyapunov function. Simulation and tests on a motor platform demonstrate that the proposed position sensorless algorithm can track speed rapidly and accurately without overshooting. The proposed sensorless control can ensure the control stability of PMIWMs and can be applied in other occasions where installing motor sensors is challenging.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560474","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}

The approach is essentially based on extracting acceleration peak signals and applying a saturation function. The observer structure employs acceleration measurements and combines velocity loop input and control quantity to acquire peak signals. Differing from the general disturbance observer, the extraction of acceleration peaks is used to quickly capture the change in error and effectively reduce the impact of signal noise for the observer implementation. To trade off the observer bandwidth and the system stability, a partial compensatory scheme of limiting the filter output with a nonlinear saturation function is adopted. The relationship between the saturation threshold and the filter bandwidth is analyzed for optimal balance. It is theoretically and experimentally proved the effectiveness of NOADOB in attenuating error peaks. Moreover, the proposal accelerates the dynamic response to peak disturbances, breaks through the constraint of accurate modeling, and improves disturbance rejection performance.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545340","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 these issues, this study proposes multi-dimensional synchronous feature mode decomposition (MSFMD) method, a novel approach that combines multi-channel signal synergy with advanced decomposition and feature extraction techniques. The MSFMD method operates through a systematic framework comprising three key steps: custom-designed spectral segmentation strategy based on order statistic filter, synchronized decomposition of multi-channel signals with spectral alignment constraint, adaptive mode screening based on time-frequency correlation coefficients and envelope spectral kurtosis. Tailored for the channel signal, initial filter banks are decided. Then, the same fault-feature-oriented modes keep the spectral alignment constraint across channels, capturing inter-channel correlations while reducing noise and redundant modes. The adaptive screening strategy selectively retains fault-relevant modes, significantly improving the robustness and interpretability of the extracted features. MSFMD is able to effectively amplify weak fault features, handle complex multi-fault conditions, and improve computational efficiency under high-noise environments. Compared to traditional methods such as feature mode decomposition (FMD) and multivariable variational mode decomposition (MVMD), MSFMD demonstrates superior performance, such as susceptibility to noise, redundancy, and inefficiency in multi-fault scenarios. Validation through complex fault experiments confirms MSFMD's capability to provide accurate and reliable diagnostics.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143574942","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}

The notions of robust GKL-stability, R-FT-ISS, and R-FTS are proposed. Time-based IHC (T-IHC) and state-based IHC (S-IHC) are proposed, respectively. And based on the Hamilton-Jacobi inequalities of Lyapunov-like functions, less restrictive R-FT-ISS and R-FTS criteria are established for UDS under IHC (including T-IHC and S-IHC). And the event-triggered S-IHC schemes for R-FT-ISS and R-FTS are designed. Correspondingly, the estimates of settling time for R-FT-ISS and R-FTS are also obtained, respectively. Theoretical results and numerical simulations show that both T-IHC and S-IHC can achieve not only R-FT-ISS but also R-FTS for unstable systems with structural disturbances and external disturbances. Therefore, IHC (including T-IHC and S-IHC) can eliminate the impact on stability from disturbances and thus both T-IHC and S-IHC are anti-disturbance and robust, which improves the stabilization only to ISS (not to asymptotic stability) in the presence of disturbance in the literature. It is also shown that R-FT-ISS and R-FTS can be achieved by pure impulsive control, which improves the FTS results of impulsive systems in the literature. Moreover, compared with T-IHC, S-IHC has less number of impulses and lower cost than T-IHC while T-IHC has smaller settling time.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538265","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}

This paper investigates safety prescribed performance control (SPPC) for VC trains with multifold kinematic targets and switching constraints (SCs). In comparison to traditional continuous PPC methods, SPPC strategy incorporating discontinuous characteristics is designed to ensure that position and speed errors of VC train formation remain within the maximum overshoot limit within a finite time after the mutation of tracking target. It is achieved by separating the analysis of continuous intervals and discontinuous impulsive points, which ensures the stable properties of the closed-loop system through utilizing the Lyapunov method and strict mathematical justification. To ensure the safe train operation, multiple kinematic targets are considered throughout the entire process, from un-formation to final cooperative VC formation. To avoid the occurrence of unstable switching before the completion of the formation, the monitor output for the mode partition is made subject to the joint effect of position and speed targets. By imposing a minimum dwell time constraint, the train's real-time running state does not switch frequently within a single mode, which eliminates the Zeno phenomenon. Finally, based on implementing several scenarios for multi-train VC formation adhering to SCs, and incorporating the sample data sourced from the high-speed G1 train traversing from Beijing South Railway Station (BSRS) to Jinan West Railway Station (JWRS), the effectiveness of mode partition and the theoretical results in train operations are verified in numerical simulations.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538266","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}

This event has a major impact on the stability of the power grid. The recent research has been mainly concentrated on identifying the parameters of sub-synchronous oscillation. Sub/Super synchronous oscillations (Sub/Sup-SO) simultaneously occur, increasing the difficulty in accurately identify the parameters of SO. This work presents a novel method for parameter identification that effectively handles the Sub/Sup-SO components by utilizing the Rife-Vincent window and discrete Fourier transform (DFT) simultaneously. To mitigate the impact of spectral leakage and the fence effect of DFT, we integrate the tri-spectral interpolation algorithm with the Rife-Vincent window. We use the instantaneous data of the phasor measurement unit (PMU) to identify Sub/Sup-SO-related parameters (Sub/Sup-SO damping ratio, frequency, amplitude and phase). First, the spectrum of the Sub/Sup-SO signals is analyzed after incorporating the Rife-Vincent window, and the characteristics of the Sub/Sup-SO signal are determined. Then, the signal spectrum is identified using a three-point interpolation algorithm, and the damping ratio, amplitude, frequency, and phase of the Sub/Sup-SO signals are obtained. In addition, we consider the identification accuracy of the algorithm under various complex conditions, such as the effect of Sub/Sup-SO parameter variations on parameter identification in the presence of a non-nominal frequency and noise. The proposed algorithm accurately identifies the parameters of multiple Sub/Sup-SO components and two Sub-SO components that are in close proximity. Testing with synthetic and real data demonstrates that the proposed algorithm outperforms existing methods in terms of identification accuracy, identification bandwidth, and adaptability.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":"166-180"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140960142","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}
