This paper analyzes the instability of the filtering system of the initial alignment under a quasi-static base and points out the great influence of Kalman filtering initial value setting on the filtering results. This is instructive for many conditions under initial alignment and integrated navigation. Meanwhile, an improved method for the alignment of large misalignment angles is proposed by replacing the body-frame bias state with the geographic-frame bias state. Simulation experiments show that it can improve the horizontal alignment accuracy by 0.1°and vertical alignment accuracy by 1.6°. © 2023 Concern CSRI Elektropribor, JSC.

Traffic accidents pose significant social and economic challenges, making effective accident prediction systems essential. Traditional machine learning methods often struggle to capture the complex, nonlinear patterns in visual accident data. Recent advancements suggest that deep learning offers a promising solution to this challenge. These vision-based systems rely on object detection as a foundational step, identifying key entities in traffic scenes captured by cameras to improve prediction accuracy. Despite its importance, the impact of object detection accuracy on overall accident prediction effectiveness remains underexamined. This study investigates this relationship through cross-dataset analysis. Experimental results show that object detection accuracy directly impacts accident prediction performance, with training dataset choice playing a critical role. Enhancing model generalization is essential to stabilizing accident prediction systems.

This article investigates a fractional-order coupled Hindmarsh-Rose neural networks model. Firstly, the existence and stability of an equilibrium point in the system are verified. Then, the periodic bifurcation behavior of the system on a two-parameter plane is studied, and numerical simulations show the existence of both non -chaotic and chaotic plus periodic bifurcation behavior on the two-parameter plane. Finally, a feedback controller was designed to stabilize the bifurcation point of the delayed system and increase the stable range of the system. © 2023 Technical Committee on control Theory, Chinese Association of automation.

To enable safe and efficient autonomous navigation of unmanned ships in complex marine environments, particularly when encountering overtaking, head-on, or crossing scenarios, it is crucial to accurately identify and detect unknown unmanned vessels. This paper proposes a lightweight object detection algorithm tailored to these challenges. The lightweight network Ghostnet is used to improve the backbone network of the YOLOv5s algorithm, achieving lightweight target detection. By introducing the ECA attention mechanism, the model can better focus on important information in the image, enhancing the ability of feature representation, and improving the model's capability for complex scene understanding and target recognition and localization. Finally, the MPDIoU is used as the bounding box loss function for the YOLOv5s algorithm, which not only improves convergence speed but also obtains more accurate regression results. Comparative experiments show that the proposed improved algorithm outperforms models such as YOLOv5-BiFPN, YOLOv5-CBAM, and YOLOv5-SE in terms of model size, computational complexity, parameter count, detection speed, and average precision. © 2025 SPIE.

With the rising demand for more flexibility and larger workspaces in collaborative robots, rigid-flexible coupling robotic systems have garnered increasing attention. This study focuses on trajectory tracking and vibration suppression for RFCRSs operating in 3D space. The nonlinear coupling between angular joint positions and flexible structural displacement leads to complex vibration behaviors. To address this issue, the assumed mode method is employed to curve-fit the first-order modal shape of the flexible arm, resulting in a shape function. This approach simplifies the nonlinear infinite-dimensional dynamics of RFCRSs into a fourth-order dynamical system. The reference trajectory is planned using the polynomial programming method based on the established kinetic model. The reference trajectory is tracked with a model reference adaptive control (MRAC) method to reduce the robot end vibration. Finally, the effectiveness of the robot model reduction method and the associated control strategy is validated through a comparison with PD control and MRAC, which does not account for arm flexibility. © Published under licence by IOP Publishing Ltd.

Full-State Prescribed Performance-Based Consensus of Double-Integrator Multi-Agent Systems with Jointly Connected Topologies

This paper addresses the full-state prescribed performance-based consensus problem for double-integrator multi-agent systems with jointly connected topologies. To improve the transient performance, a distributed prescribed performance control protocol consisting of the transformed relative position and the transformed relative velocity is proposed, where the communication topology satisfies the jointly connected assumption. Different from the existing literatures, two independent transient performance specifications imposed on relative positions and relative velocities can be guaranteed simultaneously. A numerical example is ultimately used to validate the effectiveness of proposed protocol. Copyright © 2024, The Authors. All rights reserved.

Oscillation is a significant indication of the deterioration of control system performance and needs to be carefully monitored to ensure safe and stable process operations. However, industrial processes are often prone to noisy artifacts and nonstationary trends, resulting in low signal-to-noise ratios. In order to tackle this problem, this study introduces a novel framework for enhanced trend removal and noise reduction, which is featured by the following steps:(i) The circulant singular spectrum analysis (CiSSA) is used to decompose oscillation data into several reconstructed components (RCs). (ii) The estimated power spectral density (PSD) ofthese RCs is then smoothed using the Savitzky-Golay filter (SGF) to eliminate noise and identify the RCs corresponding to oscillatory components. (iii) These identified RCs are subsequently reconstructed to produce purified oscillatory data. The effectiveness of the suggested approach is validated using simulations and real-world industrial case studies. The findings indicate that the method notably enhances the quality of oscillatory data. © 2024 IEEE.

In this paper, we consider a continuous system cooperative dynamic game problem with two players. Through the introduction of dynamic programming concept, a Hamilton-jacobi-Belman equation for two players is designed. By introducing detection noises and using the basis function approximation method, a data-driven adaptive dynamic programming method is proposed and an iterative equation is obtained. Then, by introducing two detection noises and using the basis function approximation method, an iterative equation is obtained. It is note-worthy that we can obtain the Nash equilibrium solution of the cooperative game. Finally, a numerical simulation example is given to demonstrate the effectiveness of the proposed adaptive dynamic programming approach. © 2023 Technical Committee on control Theory, Chinese Association of automation.
