In this work, we focus on fast-slow delayed dynamical systems, which are usually described by coupled delayed differential equations with two-time scales. The purpose of this article is to propose a data-driven discovery method to identify the fast-slow delayed differential equations from noisy measurements. The proposed method blends delay dictionary-based sparse identification of nonlinear dynamics (SINDy) framework and a fixed interval sampling strategy. Specifically, we leverage the SINDy methodology to describe the fast-slow delayed differential equations by a few active terms of a large dictionary containing the delay terms and many candidate nonlinear basis functions. To identify the active terms and the corresponding coefficients, a sequential thresholded re-weighted ℓ 2 least squares algorithm is used to solve the resulting sparse regression problem to enhance the sparsity. Once a sparse model with fixed delay is selected, the proposed method further estimates the delayed time by calculating the reconstruction error from the sparse model until the one that makes the reconstruction error minimum. We verify the effectiveness of the proposed method with several classical fast-slow coupling delayed systems. The experimental results show that the proposed method can well automate the fast-slow delayed differential equations from noisy data and the delayed terms also can be detected accurately.

Interest in autonomous driving (AD) and intelligent vehicles (IVs) is growing at a rapid pace due to the convenience, safety, and economic benefits. Although a number of surveys have reviewed research achievements in this field, they are still limited in specific tasks and lack systematic summaries and research directions in the future. Our work is divided into 3 independent articles and the first part is a Survey of Surveys (SoS) for total technologies of AD and IVs that involves the history, summarizes the milestones, and provides the perspectives, ethics, and future research directions. This is the second part (Part I for this technical survey) to review the development of control, computing system design, communication, High Definition map (HD map), testing, and human behaviors in IVs. In addition, the third part (Part II for this technical survey) is to review the perception and planning sections. The objective of this paper is to involve all the sections of AD, summarize the latest technical milestones, and guide abecedarians to quickly understand the development of AD and IVs. Combining the SoS and Part II, we anticipate that this work will bring novel and diverse insights to researchers and abecedarians, and serve as a bridge between past and future.

In this paper, we analyze the response of passive quantum linear systems in a non-Markovian environment to single photon input fields. Based on an augmented modelling method for non-Markovian quantum systems, analytic forms of output intensity and output covariance function in steady-state are derived. These results allow us to quantitatively analyze the influence of non-Markovian environment on system response under a framework of linear system theory.

Cloth-like items are ubiquitous in both daily life and industrial production, but their softness makes them difficult to manipulate. This paper focuses on solving the problem of automatic manipulation especially in the scenario of flat surface by introducing a novel end-effector mechanism. The gripper utilizes a modular design concept, enabling it to be reconstructed with a varying number of fingers based on specific requirements. One of the fingers has an active rolling fingertip that rolls up the object from the table to create wrinkles, for easier grasping. Additionally, there are fingertips with revolute joints that enable fine-tuning of the grasp configuration to fix the objects. To test the effectiveness of the mechanism, we manufactured a real gripper device and mounted it on a collaborative robotic arm for grasping tests. Experiments were conducted on six kinds of cloth-like objects with different materials, grasping them from above. The experimental results show that the gripper with this mechanism configuration performs well in this scenario.

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

IEEE International Conference on Micro Electro mechanical systems

In recent years, the percutaneous balloon compression (PBC) does not require craniotomy and has gradually become the preferred treatment for trigeminal neuralgia. However, there is a lack of microballoon catheters with real-time feedback capability to replace the current personal experience from X-ray pictures. This paper reports a stretchable fractal electrode array integrated on miniature semi-expanded microballoon catheter for the first time, which can accommodate large expansion. Six electrode sites are uniformly distributed in 120° circumferential direction on two ends of the microballon. Thus, the fractal electrodes can apply directional electrical stimulation with good spatial resolution to the compressed ganglion during the microballoon expansion, along with the evoked myoelectric potential to improve treatment of trigeminal neuralgia. Optimized fractal interconnects can integrate to the semi-expanded balloon with sufficient stretchability. Besides, the electrode sites with ring ground are assembled on metal marker rings without deformation for better nerve stimulation.

Gd is a highly effective element for neutron shielding, but its minimal solubility promotes Gd-rich intermetallics that degrade alloy properties if not properly controlled. This study introduces an innovative approach to refine these intermetallics to a sub-micron scale and achieve a uniform distribution by leveraging the cellular boundaries formed during laser powder bed fusion. These cellular boundaries, combined with the tailored intermetallics, act as "modulators" that effectively impede plastic deformation while permitting dislocation motion, resulting in a satisfying strength-ductility synergy. The findings offer a promising direction for incorporating elements with low solubility but functional properties by tailoring intermetallics through cellular boundary engineering. © 2025 The Author(s)

第40届中国控制会议

作者： Hantong Mei Yunhe Guo Junyan Yang Ge Zhou Yang Li School of Astronautics Northwestern Polytechnical University Shanghai Electro-Mechanical Engineering Institute Shanghai Aerospace Control Technology Institute Unmanned System Research Institute Northwestern Polytechnical University

This paper proposes a novel effective adaptive fault tolerant attitude controller for a class of HLVs（Heavy-lift Launch Vehicles） subject to external disturbances, actuator nonlinearities and faults. The dead-zone nonlinearities of the actuator, accidental actuator gain faults and deviation faults are all under consideration in this paper. In order to guarantee the accurate attitude stabilization and tracking, a fault tolerant control scheme with two adaptive parameters is constituted, which is able to estimate the lower boundary of the nonlinear actuator effectiveness, the nonlinear dead-zone parameters and external disturbances. As a result, the synthesized adaptive fault tolerant attitude controller can work well in the presence of the disturbance, actuator nonlinearities and faults. The proof of the convergence is accomplished on the basis of a quadratic Lyapunov function. The simulation results are presented to demonstrate the effectiveness and advantages of the proposed adaptive fault tolerant control method.
