Group consensus for multiple networked Euler-Lagrange systems with parametric uncertainties

In this paper,a group consensus problem is investigated for multiple networked agents with parametric uncertainties where all the agents are governed by the Euler-Lagrange system with uncertain parameters.In the group consensus problem,the agents asymptotically reach several different states rather than one consistent state.A novel group consensus protocol and a time-varying estimator of the uncertain parameters are proposed for each agent in order to solve the couple-group consensus problem.It is shown that the group consensus is reachable even when the system contains the uncertain parameters.Furthermore,the multi-group consensus is discussed as an extension of the couple-group consensus,and then the group consensus with switching topology is considered.Simulation results are finally provided to validate the effectiveness of the theoretical analysis.

金属尘化腐蚀层内应力的有限元模拟计算

通过低合金Cr5Mo在600 ℃,H2-CO混合气氛中的尘化腐蚀试验,得到碳在Cr5Mo中的扩散系数,在此基础上,利用大型有限元软件ABAQUS及其自编用户子程序(USDFLD,UEXPAN和UDIFF),开发了热-弹-塑-扩散耦合计算程序,对Cr5Mo尘化腐蚀层内应力进行了有限元模拟,并与不考虑扩散应力的内应力进行了比较.研究结果表明:Cr5Mo在尘化腐蚀过程中因碳的扩散而引起的扩散应力水平比较高;高应力区主要集中在腐蚀层表面和腐蚀层/基体界面处;扩散应力在最终的尘化腐蚀层内应力中占有相对比较大的比重,是导致腐蚀层开裂和剥落的重要原因之一.

Electrochemical behavior of adriamycin at a cobalt ion implantation modified electrode

With Co/GCE in 0.005 mol Tris/L/0.05 mol/L NaCl solution (pH 7.1), a sensitive reductive peak of adriamgcin (ADM) was obtained by the linear scan voltammetry. The peak potential is ?0.62 V (vs. SCE). The peak current is proportional to the concentration of ADM. The electrochemical behavior of the system was studied by the linear-sweep and cyclic voltammetry. The experiments showed that the reduction at Co/GCE is a quasi-reversible process with adsorption. According to Laviron’s theory, the electrode reaction rate constant k₀ and the electron transfer coefficient a are determined to be 2.15 s^-1 and 0.62, respectively. The composition of the surface, valence state of elements and depth distribution of elements on the surfaces of Co/GCE were determined by the X-ray photoelectron spectroscopy and Auger electron spectroscopy. The experiments showed that Co was surely implanted into the surface of GCE. The implanted Co element in the form of Co-C catalyzed the reduction of ADM.
