However, traditional fault detection technologies still heavily rely on additional sensors. The resulting enormous cost of sensors restricts the application of those technologies. Given this situation, a self-sensing fault detection framework to explore the weak fault impulses of the planetary gearbox is presented without additional sensors. In this framework, we first capture the preliminary signals from the servo control systems. Then, the hole control model of the motor driving planetary gearbox is constructed. After this step, the feasibility of fault detection for the planetary gearbox through the motor servo control signals is investigated. With the measured servo control signals, a multi-signal assisting adaptive time synchronous averaging method is first proposed to explore fault impulses. This method first introduces a periodic enhanced Gini to select optimal parameters adaptively. Finally, experiments on a weak fault of three components in the planetary gearbox are carried out separately, certifying our framework's validation of planetary gearbox fault detection. This framework hopes to provide a novel scheme for the weak fault self-sensing of planetary gearboxes.</span></div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"165 ","pages":"Pages 358-371"},"PeriodicalIF":6.5,"publicationDate":"2025-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144277144","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}

As the number of agents increases, multi-agent systems (MAS) in a large-scale and high-density topology demand higher resources, which consequently degrades efficiency of consensus. Existing approaches that consider only direct point-to-point neighbors may overlook potential topological information, further hindering consensus performance. To achieve fast consensus in large-scale and high-density topologies, a framework named Homogeneous Connections Based on Agents State Fusions MAS (HCASFMAS) is proposed. The framework extracts broader topology information of consensus degree by fusing states of two-hop neighbors. Leveraging homogeneous idea, agents establish homogeneous connections with neighbors that exhibit a higher consensus degree, ultimately accelerating the consensus process while preserving connectivity. First, a neighbor selection strategy based on consensus degree of agent state fusion is introduced to construct candidate neighbors, aiming to reduce redundant connections. Second, an adaptive </span>consensus algorithm is formulated to flexibly adapt to the distribution of neighbors. Finally, a candidate constraints set is established to accelerate consensus by expanding the scope of constraints while preserving connectivity. In this study, connectivity and convergence of the system are theoretically analyzed from a geometric perspective. Simulation experiments are conducted to compare the proposed method with existing approaches under different densities and topologies. Simulation results demonstrate the superiority of this method in achieving fast convergence, particularly in large-scale and high-density scenarios.</div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"165 ","pages":"Pages 27-39"},"PeriodicalIF":6.5,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512862","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}

Notice that highly underdamped oscillation and rate-dependent hysteresis exist in the EMMS, so it is a complex nonlinear dynamic system. In order to control the deflection angle of the EMMS using the internal model control strategy, it is necessary to establish the inverse model of the EMMS. Therefore, a new model structure that is convenient for inversion is proposed in this paper to describe the characteristics of the EMMS with underdamped and rate-dependent hysteresis. In the proposed scheme, the model is a combination of a group of weighted sub-models based on the segmentation of the system's operating frequency. The weight of each segmented sub-model is not a constant but a new type of function which is also called the smoothing factor. Its function is to smooth the switching between sub-models, thereby reducing the dynamic error caused by model switching. In addition, the </span>particle swarm optimization<span> (PSO) algorithm is used to determine the optimal frequency segmentation points, which helps to obtain the optimal model for describing the system characteristics. Based on the proposed segmented combination model, the corresponding segmented internal model control with two-degree-of-freedom filters is proposed, and the corresponding filters in the internal model control are designed based on the small gain theorem. Finally, the proposed control strategy is applied to the control of the deflection angle of the electromagnetic micro-mirror to verify the proposed control method. Moreover, the non-smooth internal model control strategy is also used for comparison in the experiments.</span></span></div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"165 ","pages":"Pages 408-421"},"PeriodicalIF":6.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144277143","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}
