IMC-PID Controller Design for Linear Systems with Parametric Uncertainties [PDF]
, 2015 控制系统控制品质的好坏直接决定了生产品质和效益，而工业过程控制中 百分之九十以上的控制器仍是PID控制器。于是，PID控制器参数整定一直以 来是工程应用和理论研究的核心问题之一。众多PID整定法中，IMC-PID控制 器参数整定方法脱颖而出，越来越广受工业控制过程的青睐。原因在于，基 于IMC的PID控制器对模型要求较低，甚至在高阶低阶、不稳定或非线性等情 况下，它都能获得有效的控制品质。而且IMC-PID仅有一个整定参数，该参数 调整与系统动态品质和鲁棒性的关系比较明确，从而无需繁杂的整定就可以使 ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

The Analysis of Defect Product Recall Law System [PDF]
, 2016 内容摘要 缺陷产品召回制度是一项重要民法规则，自从上个世纪60年代在美国首先确立以后，许多国家也在各自的国家法律体系中建立起这项制度。近年来，产品质量、产品安全的问题屡有发生，给消费者生命、财产带来极大的损害，缺陷产品召回制度受到各国的普遍关注。与欧美等国对产品召回制度设立较早，且目前已经相对完善比较，产品召回制度这项重要的民法制度在我国法律体系中所占的位置和比例是不相称的。本文通过对美国的缺陷产品召回法律制度进行研究与探讨，借鉴它们的健全的法律体系，比较分析我国缺陷产品召回制度的经验与不足 ...
