According to the transfer impedance getting from distributed parameter model,we analyse the influences of the number of turns,capacitance to the shield and interturn capacitance on the high frequency characteristic of Rogowski coil through theories and simulations. Simulation shows that there are a series of zeros in high frequency band, but on the whole, the high frequency response does not change with the increase of frequency. The number of turns and capacitance to the shield can influence the frequency at which zero appears, but the high frequency characteristic of Rogowski coil can't be influenced. Considering the interturn capacitance, the curve of high-frequency response characteristic presents a "V" shape", and this leads to the reduction of higher cut-off frequency. So we should try to decrease the interturn capacitance to reduce the influence on the high frequency characteristic.

This paper proposes a single-wire power transfer (SWPT) system using distributed parameter resonant coil. An accurate equivalent circuit is proposed by establishing the distributed parameter circuit model of the single-layer air-core solenoid coils and the single wire. The vector and amplitude distribution of spatial electric field are depicted from simulation results. Experimental results of a prototype SWPT system are presented at different distances. The system can transfer 350W with 60% efficiency at 30m, and transfer 300W with 42% efficiency at 70m.

This paper presents an analysis method, based on MacCormack＇s technique, for the evaluation of the time domain sensitivity of distributed parameter elements in high-speed circuit networks. Sensitivities can be calculated from electrical and physical parameters of the distributed parameter elements. The proposed method is a direct numerical method of time-space discretization and does not require complicated mathematical deductive process. Therefore, it is very convenient to program this method. It can be applied to sensitivity analysis of general transmission lines in linear or nonlinear circuit networks. The proposed method is second-order-accurate. Numerical experiment is presented to demonstrate its accuracy and efficiency.

In this paper, we present a model of distributed parameter estimation in networks, where agents have access to partially informative measurements over time. Each agent faces a local identification problem, in the sense that it cannot consistently estimate the parameter in isolation. We prove that, despite local identification problems, if agents update their estimates recursively as a function of their neighbors' beliefs, they can consistently estimate the true parameter provided that the communication network is strongly connected;that is, there exists an information path between any two agents in the network. We also show that the estimates of all agents are asymptotically normally distributed. Finally, we compute the asymptotic variance of the agents' estimates in terms of their observation models and the network topology, and provide conditions under which the distributed estimators are as efficient as any centralized estimator.

In this note we consider the closed-loop control of an aeroelastic torsion model where the control objective is to track a desired shape. A Lyapunov approach is utilized and an adaptive control algorithm using e-modification is proposed. The entire analysis is confined to the underlying infinite dimensional space and uniform ultimate boundedness of the closed-loop system is proved. Numerical simulation is provided to illustrate the performance.

In this paper, we propose a mathematical model for an electromagnet placed inside a molding machine and design a PI controller for this system. The eddy currents inside the electromagnet are a spatially-distributed phenomenon that is difficult to capture by using finite-dimensional systems. First, based on an expression of the system as partial differential equations, we analyze essential properties of the system. From the analysis, we derive a suitable model for a control system design in the frequency domain. Second, we propose a new loop shaping technique that utilizes GKYP lemma for this system.

This paper studies the consensus control of nonlinear impulsive distributed parameter multi-agent sys-tems (IDPMASs), whose dynamic behavior depends on time and space. First, to achieve the complete consensus for nonlinear parabolic IDPMAS, a distributed P-type iterative learning consensus control pro-tocol is proposed that includes network topologies information and nearest neighbor knowledge. Using impulsive Gronwall inequality and mild solution formula based on operator semigroup, the rigorous con-vergence analysis of consensus errors is provided, and convergence conditions are established as well. Furthermore, the consensus control of nonlinear second-order hyperbolic IDPMAS is investigated that employ an open-closed-loop P-type consensus control protocol, which uses both currents iterative con -sensus error and last iterative consensus error. The theoretical result of this paper shows the consensus errors between any 2 agents can converge to 0 with the increase in iterations under given conditions. Finally, two numerical simulations are given to demonstrate the effectiveness of the proposed methods.(c) 2023 European Control Association. Published by Elsevier Ltd. All rights reserved

A renovating method for distributed parameter control systems with constants, varying-delays, and multi-varying-delays is put forward. By constructing average Lyapunov functions and employing linear matrix inequality (LMI) and other matrix inequality technologies, several sufficient conditions for exponential stabilization are derived. In this method, the conditions are delay-dependent and at the same time, the upper-bound of exponential convergence rate is obtained. In addition, the distinctive advantage of our method is that the criteria mentioned in the paper are easy to check, so it can be applied to practice easily. Finally, a computation example is given to illustrate the proposed method.

In this paper, the Hamilton method is used to establish a distributed parameter model for a single-link flexible robotic arm based on the form of partial differential equations. The distributed parameter system is used to control the model. The boundary control method is used to add a boundary control input to the end boundary of the manipulator. The PD boundary controller is designed, and the distributed parameter boundary control based on the exponential convergence method is performed on the end boundary of the manipulator to adjust the vibration of the robotic arm. The Lyapunov function is designed to prove the stability of the system through calculation.
