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 ：
Conventional microgrids that employ droop control may experience challenges related to frequency and voltage offsets, which can pose risks to power system safety. Furthermore, the use of continuous communication in traditional control systems can result in technical and financial challenges. This paper introduces a fixed-time dynamic event-triggered secondary control for islanded microgrids, designed to achieve frequency restoration, voltage regulation and active power sharing within a specified timeframe. This distributed control approach relies solely on information from each distributed generator(DG) and its neighbours. Each DG receives communication from its neighbours and concurrently broadcasts its own information only when certain deviation were reached, thereby minimising communication costs. Several simulated instances illustrate the usefulness and robustness of this control method, including scenarios involving load changes, time delay and topology switching.

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 ：
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 ：
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.

Abstract ：
The leader-following consensus of linear heterogeneous multiagent systems is investigated in this paper. To comply with the most practical scenario, the communicating topologies among agents are assumed to switch stochastically and driven by a continuous-time discrete-state Markov process, whose state space corresponds to all the possible topologies. A novel distributed adaptive compensator is designed for the followers to reconstruct the exogenous signals without knowing the Laplacian matrix who is regarded as a global information, and sufficient conditions are given to ensure the compensator converges to the dynamic of the leader asymptotically in the mean square sense. Then, based on the compensator, we solved the consensus problem both by distributed state and measurement output feedback control schemes under output regulation framework, which allow followers to have nonidentical state dimensions. Finally, the theoretical results are demonstrated by a numerical example.

Abstract ：
The economic dispatch problem (EDP) in smart grid mainly is investigated in this paper. The transmission losses of power produced by generator will be taken into account, which introduces nonlinear constraints in the EDP. By viewing the losses as a quadratic function, a broadcast gossip economic dispatch algorithm is proposed to work out the EDP. This distributed algorithm makes all neighbors of the node update the information of each iteration through broadcast. The convergence of the algorithm will be certified by the approximation as well as matrix perturbation theory. Three simulation experiments show the distributed algorithm’s availability as well as plug-and-play capability, and a comparison with the algorithm in which the transmission loss is not considered is further given. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract ：
This article studies the finite-time consensus control of a multi-agent system, and the trigger method adopts event trigger. A finite time controller that uses first-order neighbor information and second-order neighbor information to trigger events is designed. It was subsequently proved that the system can reach a consensus within a limited time under the event-triggered control protocol, and at the same time eliminate Zeno behavior through periodic sampling. The application of second-order neighbor information speeds up the convergence speed of the system. In addition, the introduction of the state combination measurement method can advantageously reduce the number of controller updates. Finally, a case is given to explain the validity of the proposed theory. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
