Science China(Information Sciences) 2025年第1期68卷 292-305页

This article proposes a distributed dynamic event-triggered data-driven iterative learning control(DET-DDILC)scheme under a predefined performance to tackle the bipartite tracking control problem for multiagent systems(MASs). An improved dynamic linearization technique is utilized to convert the nonlinear MASs into an iterative linear data model. First,a peer-to-peer mapping function is introduced to map the constrained distributed system output homeomorphism to an unconstrained one. In addition, a DET mechanism based on a time-iteration-varying function is devised to conserve network communication resources. Based on the unconstrained transformation and the designed DET mechanism, the DET-DDILC algorithm is devised to ensure that the bipartite tracking performance of MASs can be within the preset range. Finally, the effectiveness and feasibility of the designed control scheme are demonstrated via a simulation case by a comparison.

松软煤体钻孔稳定性与塌孔机理分析

能源与节能 2021年第10期 67-68页

作者：韦瑞敏山西寿阳潞阳麦捷煤业有限公司山西寿阳045400

在瓦斯抽采工程中,需要施工大量的煤层钻孔。然而,由于煤层松软钻孔的成型和稳定性差,严重制约了钻孔施工和抽采的效率。通过对影响松软煤体钻孔稳定性的因素进行分析,探讨了钻孔塌孔的机理,以期为瓦斯抽采钻孔的施工提供一定的指导。

为评价重金属镉(Cd)污染地区辣椒种植的安全性,通过Cd污染土壤盆栽和小区试验研究了71个辣椒品种对Cd累积的差异,并探讨土壤中Cd含量对辣椒中Cd含量的影响,以期获得辣椒安全种植的土壤Cd含量值并筛选出低Cd累积辣椒品种资源。结合盆栽试验和小区试验结果,初步认为在土壤Cd含量低于0.58 ***^(-1)时,湘辛8号、长研201、长辣7号、星秀朝天椒和博辣9号中Cd含量均低于国家现行标准GB 2762-2012。还考察了湘研15号辣椒不同坐果时期Cd含量的变化,发现在不同坐果时期对Cd的含量存在明显差异,因此在辣椒育种过程中应同时考虑辣椒采摘时间对Cd积累的影响。
