In this paper, we investigate a leader-following tracking problem for multi-agent systems with bounded inputs. We propose a distributed bounded protocol for each follower to track a leader whose states may not be completely measured. We theoretically prove that each agent can follow the leader with estimable track errors. Finally, some numerical simulations are presented to illustrate our theoretical results. 相似文献

A series of triethylammonium halides (Et3NHCl, Et3NHBr, and Et3NHI) was synthesized. The crystal structures of the three compounds were characterized by X-ray crystallography. The lattice potential energies and ionic radius of the common cation of the three compounds were obtained from crystallographic data. Molar enthalpies of dissolution of the compounds at various values of molality were measured in the double-distilled water at T = 298.150 K by means of an isoperibol solution-reaction calorimeter. According to Pitzer’s theory, the values of molar enthalpies of dissolution at infinite dilution and Pitzer’s parameters of the compounds were obtained. The values of apparent relative molar enthalpies, relative partial molar enthalpies of the solvent and the compounds at different molalities were derived from the experimental values of molar enthalpies of dissolution of the compounds. Finally, hydration enthalpy of the common cation Et3NH+ was calculated to be ΔH+ = ?(150.386 ± 4.071) kJ · mol?1 by designing a thermochemical cycle. 相似文献

A quantum dialogue protocol, based on the two-qutrit entangled states is proposed in this paper. In this protocol, the security of communication is ensured by the secret transmitting order of qutrits. Two legitimate users can directly transmit their secret messages by generalized Bell-basis measurement and classical communication. The efficiency of our scheme is high, which can reach to 100 %. Besides, the protocol is not only feasible in practice but also can discard the drawback “information leakage” or “classical correlation”. 相似文献

Lattice potential energy and standard molar enthalpy in the formation of 1-dodecylamine hydrobromide (1-C12H25NH3 ·Br)(s) 下载免费PDF全文
This paper reports that 1-dodecylamine hydrobromide (1--C12H25NH3·Br)(s) has been synthesized using the liquid phase reaction method. The lattice potential energy of the compound 1--C12H25NH3·Br and the ionic volume and radius of the 1--C12H25NH3+ cation are obtained from the crystallographic data and other auxiliary thermodynamic data. The constant-volume energy of combustion of 1--C12H25NH3·Br(s) is measured to be Δc Umo(1--C12H25NH3·Br, s) =--(7369.03±3.28) kJ·mol-1 by means of an RBC-II precision rotating-bomb combustion calorimeter at T=(298.15±0.001) K. The standard molar enthalpy of combustion of the compound is derived to be Δc Hmo(1--C12H25NH3·Br, s)=--(7384.52±3.28) kJ·mol - 1 from the constant-volume energy of combustion. The standard molar enthalpy of formation of the compound is calculated to be Δf Hmo(1--C12H25NH3·Br, s)=--(1317.86±3.67) kJ·mol-1 from the standard molar enthalpy of combustion of the title compound and other auxiliary thermodynamic quantities through a thermochemical cycle. 相似文献
