This paper investigates the output consensus problem for a class of nonlinear multi-agent systems (NMAS) with actuator and sensor faults. Firstly, a novel structural design method, combining parameter separation and function recombination, is introduced to address the challenges arising from multiple sensor faults. Secondly, a fuzzy logic system (FLS) is employed to approximate unknown functions. Then, a second-order tracker differentiator (TD) is used to eliminate the explosion of complexity in backstepping. Subsequently, the Nussbaum function is utilized to address the unknown control orientation. Based on backstepping technique, an adaptive fuzzy fault-tolerant consensus control (FTCC) method is proposed to remove the difficulties of sensor and actuator faults. It is confirmed that all signals in the closed-loop NMAS are bounded, ensuring the convergence of the output consensus error to an arbitrarily small neighborhood of the origin. Finally, the simulation experiment verifies the efficacy of the proposed controller. © 2024 Technical Committee on Control Theory, Chinese Association of Automation.

The development of unmanned transportation technology has improved operational efficiency and safety in open-pit mining areas. However, there remain significant challenges to be addressed. One pressing issue is the need for mining trucks to pass through the area where the cable is laid on the ground. Accidentally crushing or damaging these cables would lead to significant risk to the mining area operation. However, due to the complexity of the mining environment and the characteristics of cables being thin and curved, the existing methods such as edge segmentation are difficult to meet the requirements for cable segmentation. This paper introduces a cable segmentation method based on Mask2Former and carries out comprehensive experiments to examine the effectiveness of the method. Experimental results show that the proposed method achieves IoU of 66.04% and PA of 80.08%, which can meet the requirements of practical applications. © 2024 IEEE.

With the continuous improvement of the precision of the inertial measurement unit (IMU), the error caused by the traditionally neglected disturbing gravity to the actual navigation cannot be ignored in the high-precision inertial navigation system (INS). This paper focuses on the mechanism of the influence of disturbing gravity on actual inertial navigation. Specifically, by deriving the error propagation equation of strapdown inertial navigation system (SINS) under the consideration of disturbing gravity, we have completed the analysis of error propagation characteristics under different conditions through simulation. Furthermore, we completed the analysis of the influence characteristics of the disturbing gravity on the long-range flighting vehicle navigation errors and clarified the coupling influence mechanism of the disturbing gravity on the navigation accuracy. © 2023 IEEE.

In this study, we tackle the path-tracking problem of a nonlinear four-wheel steering vehicle dynamics model subject to model mismatches and propose a model predictive control (MPC) algorithm based on an event-triggered mechanism (ET-MPC). The goal is to maintain closed-loop control performance while reducing the computational and communication burdens of traditional MPC. We introduce an ET-MPC framework utilizing a model-free reinforcement learning agent with proximal policy optimization (PPO). This agent interacts with the MPC system, progressively learning to determine the optimal event-triggered mechanism. To enhance exploration and training efficiency, we incorporate the Long Short-Term Memory (LSTM) technique into PPO. Experimental results show that the proposed ET-MPC framework, combined with reinforcement learning for reward optimization, demonstrates superior overall performance in path-tracking control of four-wheel steering vehicles. © 2024 IEEE.

Time-sensitive software-defined network (TSSDN) not only have the networking flexibility of software-defined network (SDN), but also have the advantages of time-sensitive network (TSN). This technology provides real-time guarantees for time-triggered traffic in time-sensitive systems by limiting nondeterministic queuing delays for time-sensitive traffic. However, the effectiveness of some low-latency indirect paths may be affected when network topology changed if the information of network device changes cannot be delivered in a timely and reliable manner, and then the performance and reliability of the entire network will be affected. Therefore, we first discuss and summarize the integration issues of TSN and SDN in the control plane, focus on outlining the architectural differences of existing designs especially. Then we propose a scheme to build the control plane over TSN. The advantage is this scheme can improve the unreliable transmission problem of network performance and the reliability related information by using the characteristics of TSN, such as low delay and high reliability. We summarize our scheme as fully time-sensitive software-defined network (FTSSDN) and elaborate on each functional level. Another proposal also been raised to replace all non-TSN devices working in the forwarding plane with TSN capable devices to avoid the occurrence of nondeterministic connections. © 2023 IEEE.

In VANETs, the important and effective applications of vehicle localization include safety and communication applications. Thus, it is difficult to get very accurate localization in the dynamic and often very fluctuating environment of VANET. This research responds to this challenge with a keen thrust on improving vehicle localization using the Mobility Data Verification process. The primary goal of this work is to achieve high accuracy of vehicle positioning within VANET by checking the coherence of mobility data of moving vehicles. Hence, we present a concept that builds upon Mobility Data Verification to provide real-time location details from vehicles. Both GPS and onboard sensors feed this method, which uses a multi-level verification to flag out or eliminate the errors of deliberately spoofed data points. We use simulations to evaluate and validate the effectiveness of the proposed verification approach. As the proposed system, our previously developed and fine-tuned weighted localization (OWL) strategy does so. The performance evaluation results suggest that our proposed solution is feasible to distinguish automobiles that are not trustworthy and improve the performance of the localization algorithm. © 2024 IEEE.

Finding Misstatement Accounts in Financial Statements through Ontology Reasoning

引用

IEEE Access 2024年 1-1页

Finding misstatement accounts in financial statements, is a key problem of fraud detection. Potential applications include external audit, internal controls, investment decision and securities market regulation. However, most existing intelligent methods just detect financial statements fraud at the company level, while little research can detect financial statements fraud at the account level. For this, to achieve intelligent fraud detection at the accounts level, an ontology-based fraud detection framework was proposed. To be specific, the proposed framework mainly combines the articulation between different accounts and periods, and 30 financial indicators (ratios) as the knowledge basis of ontology. Notably, with OWL (Ontology Web Language), SWRL (Semantic Web Rule Language) and Protégé ontology editor, the case study not only completed the fraud detection in a fast and timely manner, but also provided logical explanation and risk warning at the accounts level. This fully shows the great advantages and applicability of the proposed framework in the detection of misstatements accounts. Moreover, the proposed framework is of great significance for timely detection, prevention and response of financial statements fraud. More importantly, the proposed framework opens-up a new direction of using ontology reasoning techniques to find misstatement accounts in financial statements, which provides an interpretable and fine-grained way for fraud detection.
