Two-dimensional Model Predictive Iterative Learning Control Scheme Based on a Two-dimensional Performance Model [PDF]
, 2013 将迭代学习控制(ITErATIVE lEArnIng COnTrOl,IlC)系统看作一类具有2维动态特性的控制系统,根据模型预测控制(MOdEl PrEdICTIVE COnTrOl,MPC)和性能参考模型控制思想,提出了一种基于2维性能参考模型的2维模型预测迭代学习控制系统设计方案.在该控制系统设计方案中,可以通过选择适当的2维性能参考模型来构造2维动态变化的设定值信号和预测控制信号,从而引导迭代学习控制系统收敛到合理的控制性能,并有效避免系统性能收敛过程中控制输入可能发生的剧烈波动 ...

Key Technologies of Performances Analysis and Optimization for Fixed Axis Transmission Assembly and Box of Wheel Loader [PDF]
, 2012 近年来国外装载机及国内高配置的装载机传动系方面的发展趋势是变速器大多为电液控制动力换档定轴式变速器，其可靠性高、寿命长、通用性好。然而其高端技术和市场目前均为国外企业所垄断，国内只是对国外变速器进行简单的仿制，且制造出的变速器达不到原变速器的性能。为了避免设计的盲目性，并为新变速器的设计提供指导，本文利用有限元和模态试验技术对某型号定轴变速器进行静动态特性分析，并对变速器箱体进行了优化设计。 首先，利用ANSYSWorkbench建立了变速器箱体的有限元模型，之后对其进行静力分析和自由模态分析 ...

Lessons from an eradication under multiple constraints of an island rat population of record density
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...
