Abstract ：
The pulse-echo signal receiving model can effectively determine a defect's axial position through the time flight of the defect echo. However, some materials or buried structures may significantly attenuate the ultrasonic- guided wave, making the defect echo challenging to observe. Compared with the pulse-echo mode, the guided wave in the pitch-catch signal-receiving model only needs to propagate a one-way distance. Its transmitted wave is more straightforward to observe. However, the pitch-catch model is difficult to judge if a defect exists in the pitch-catch model and identify the position of a defect through the transmitted wave. The paper presents a defect-induced non-axisymmetric transmitted wave model. It can balance the advantages and disadvantages of the two signal-receiving models. First, the periodic energy distribution altering rule of the non-axisymmetric torsional guided wave within a circular tube was theoretically analyzed. Second, the numerical and experimental results verified the theoretical analysis. Third, the defect-induced non-axisymmetric transmitted wave model was proposed based on its periodic energy distribution changing rule analysis to evaluate whether a defect exists, while the traditional pitch-catch models cannot achieve it. The axial and circumferential positions of a circumferential crack within a circular tube encased in concrete can be estimated using the proposed model, which is challenging to realize by the traditional pulse-echo models.

Abstract ：
With the application of distributed generators (DGs), microgrids (MGs) have gained much attention. Combined with the distributed communication of networked systems, we investigates the secondary restoration problem in islanded microgrids. The periodic event-triggered (PET) controllers are designed for voltage restoration and frequency restoration with accurate active power allocation, which can naturally avoid Zeno behavior. By means of a common Lyapunov function, a PET protocol is designed that requires only the information of neighbors for event detection. Both event-checking sampling period and event trigger parameter are taken into account to reduce computation and communication redundancy by choosing appropriate parameters. Furthermore, considering the effect of communication delay, sufficient conditions are given to accomplish the secondary control objectives with allowable delays. Switching topologies are considered in an extra discussion. Finally, the effectiveness of the proposed PET control strategies is verified by several MATLAB simulations. © 2024 Elsevier B.V.

Abstract ：
The secondary control plays an important role in ensuring the power quality of AC island microgrid. Since the traditional time-driven secondary control strategy will cause communication redundancy, the event-triggered mechanism has been widely studied. Under the event-triggered mechanism, the DG performs necessary communication only when its own triggering condition is met. This paper studies the problem of secondary voltage control under periodic event-triggered mechanism, which can restore the output voltage to the reference value. At the same time, considering that each DG has a different sampling and checking period, this is a more general asynchronous communication problem. In the stability analysis, the conditions of event detection period and event parameters to ensure the realization of secondary control are given. Finally, the effectiveness of the mechanism is verified by several simulations. © 2024 IEEE.

Abstract ：
This paper focused on the trajectory tracking control problem of multi-AUVs system. Combining the consensus theory with pinning control to design the control protocol for AUV influenced by the communication delay, uncertain state information and the external disturbance. The consensus control is used to discuss the coordinate problem with time delay and external disturbance. The cost of the communication is reduced by the pinning control. The trajectory tracking control protocol considered each follower communicated with the neighboring, estimated the external disturbance and uncertain accelerate information of leader. At least one follower could obtain the position and velocity information from the leader. The efficiency of the control protocol is proved by the numerical simulations. © 2024 SPIE.

Abstract ：
Due to the prevalence of communication link delay in communication networks, the study of communication delays in smart grids and their impact on economic dispatch is of great practical value. In this paper, a Gossip-based economic dispatch protocol perfected under constant time delay is considered, and it is proved by augmented matrix theory and matrix perturbation theory that a sufficiently small control gain parameter always exists to guarantee the convergence over a constant delay in the communication network. Iterative update rules are given when the neighboring generation units do not receive the initial state due to the time delay to ensure the optimal solution can be obtained. Finally, simulation cases are provided to verify the effectiveness and plug-and-play capability of the algorithm, as well as its feasibility for large-scale systems. © 2024 IEEE.

Abstract ：
The detection and positioning of underwater power transmission cables are crucial for the operation and maintenance of marine power transmission projects. Existing location solutions are primarily based on magnetic detection via electromagnetic induction, but often suffer from imperfections and a lack of experimental validation. This paper proposes an undersea cable location method that uses a twin triple-axis coil sensor. This method is more comprehensive and feasible and can accurately calculate the relative distance and angle between the detection base array and the undersea cable. After mathematical modeling, the feasibility of the method was verified through experiments. © 2024 IEEE.

Abstract ：
35 kV underwater cables are commonly used for the transmission of electrical energy in nearshore offshore wind farms. Investigating the loss characteristics of these cables improves in enhancing the efficiency of energy transmission. This paper presents the construction of a multi-physics coupled electromagnetic-thermal-fluid underwater cable simulation model using COMSOL software. The model aims to calculate the electromagnetic losses in each layer of the underwater cable accurately. This study examines the influences of various laying methods, seawater temperature, seawater velocity and burial depth on loss characteristics of submarine cables. The simulation results show that the electromagnetic loss of the submarine cable is spirally distributed along the cable axis. The total losses of the submarine cable increase with the increase of seawater temperature and seawater velocity. Furthermore, the losses in the shielding layer and armor layer demonstrate a decline as cable resistance surges with temperature. © 2024 IEEE.

Abstract ：
针对参考轨迹曲率变化大导致前视距离(LAD)调整不及时,使得无人船(USV)轨迹跟踪误差收敛慢的问题,本文利用轨迹跟踪几何关系,建立位置跟踪误差动态系统,引入曲率参数设计一种新型的时变前视距离(NTLAD),提出一种快速有限时间收敛的轨迹跟踪引导律(FFTC-GL),包括期望艏向引导律和期望巡航速度引导律研究,以快速准确跟踪大范围曲率的轨迹.首先,构造NTLAD的稳定约束条件,结合图解法求解NTLAD函数,实现法向误差快速有限时间收敛,并且引入曲率参数,快速准确地跟踪不同曲率的轨迹.其次,基于切向误差的有限时间技术,设计快速有限时间速度引导律,实现切向误差动态系统的有限时间稳定.最后,通过对比有限时间上确界,表明引导律对位置跟踪误差收敛的快速性.轨迹跟踪仿真表明FFTC-GL能够在有限时间内跟踪参考轨迹,保证曲线拐点位置跟踪误差快速收敛.
