Dynamic formation control for autonomous underwater vehiclesYAN Xue-feng(燕雪峰)1, GU Feng(古锋)2, SONG Chen(宋琛)1, HU Xiao-lin(胡晓琳)3, PAN Yi(潘毅)3(1. College of Computer Science and Technology, Nanjing... University, Atlanta, GA 30303, USA)Abstract:Path planning and formation structure forming are two of the most important problems for autonomous underwater vehicles (AUVs) to collaborate with each other......
on the stability estimations of liquid and amorphous phases. Gibbs free energy (ΔG) of liquid phase, which can be calculated approximately using mixing enthalpy (ΔHmix) and configuration entropy (Sconfig), was taken as a stability criterion of liquid phase. On the other hand, vacancy formation energy (ΔHh) was used to evaluate the stability of amorphous phase due to the linear relationship between......
Microstructure and formation mechanism of in-situ TiC-TiB2/Fe composite coating WANG Zhen-ting(王振廷), ZHOU Xiao-hui(周晓辉), ZHAO Guo-gang(赵国刚) College of Materials Science and Engineering... coating. Moreover, the formation mechanism was investigated. With the increase of the content of TiC+TiB2, the micro-hardness and wear resistance are also improved at the room temperature under normal......
Preparation and formation mechanism of Al2O3 nanoparticles by reverse microemulsion HUANG Ke-long(黄可龙), YIN Liang-guo(尹良果), LIU Su-qin(刘素琴), LI Chao-jian(李朝建) School of Chemistry and Chemical... of the Al2O3 nanoparticles were studied. With the increase of surfactant content, the particles size becomes larger. The agglomeration of nanoparticles was solved successfully. And the formation mechanisms......
J. Cent. South Univ. Technol. (2011) 18: 1161-1168 DOI: 10.1007/s11771-011-0818-z Consensus and formation control of discrete-time multi-agent systems WANG Jing(王婧), NIAN Xiao-hong(年晓红), WANG Hai..., trajectory tracking and formation control problems were studied. The main idea of trajectory tracking problems was to design trajectory controller such that each agent tracked desired trajectory. For a type......
