Our study is concerned with the time-varying formation tracking problem for second-order multi-agent systems that are subject to unknown nonlinear dynamics and external disturbance, and the states of the followers form a predefined time-varying formation while tracking the state of the leader. The total uncertainty lumps the unknown nonlinear dynamics and the external disturbance, and is regarded as an extended state of the agent. To estimate the total uncertainty, we design an extended state observer (ESO). Then we propose a novel ESO based time-varying formation tracking protocol. It is proved that, under the proposed protocol, the ESO estimation error and the time-varying formation tracking error can be made arbitrarily small. An application to the target enclosing problem for multiple unmanned aerial vehicles (UAVs) verifies the effectiveness and superiority of the proposed approach.

Agent的BDI模型主要基于Bratman提出的理性主体理论,未能充分体现Agent主动性的认知过程,使Agent的问题求解和心智状态之间的关系未得到充分表达,且难于编程实现。将Das等人提出的计划—注意—同时性加工—继时性加工认知过程模型引入Agent的理论研究中,建立了Agent的PASS-BDI模型,利用多价π-演算从心智状态,认知过程,整体行为等几个方面刻画了该模型的静态和动态特征,并将研究结果应用于多Agent组织中Agent行为特征的刻画。PASS-BDI模型加强了对Agent主动性认知过程的刻画,且易于编程实现。

Naturally-occurring environmental microorganisms may provide ‘green’ and effective biocontrol tools for disease management in agricultural crops. Due to the constant threat of resistant pathogens there is a pressing and continual need to search for new biocontrol tools. This study investigated the production of new analogs of WAP-8294A compounds by the biocontrol agent Lysobacter enzymogenes OH11 through biosynthetic engineering. WAP-8294As are a family of natural cyclic lipodepsipeptides with potent activity against Gram-positive bacteria. A series of genetic manipulations was therefore conducted on the accessory genes in the WAP biosynthetic gene cluster. The resulting strains containing a single-point mutation in ORF4, which was predicted to encode a 2-ketoglutarate dependent dioxygenase, produced deoxy-WAP-8294As. This result provides evidence for the function of ORF4 in catalyzing β-hydroxylation of the D-asparagine residue in WAP-8294As. In addition, six new analogs of WAP-8294As were identified by UHPLC-HR-MS/MS. This is the first attempt to produce new WAP-8294As in Lysobacter and shows that the spectrum of the biocontrol compounds may be expanded through the manipulation of biosynthetic genes.
