第25届中国控制与决策会议

Networked Control Systems （NCSs） employ digital network for transmitting control and monitoring information among system components. Control information over digital network may be delayed due to transmission and this can adversely affect the control performance. To achieve desired performance in the presence of delays the controller needs to modify its gains based on the channel delay. In this paper, we propose a simple adaptive regulator that uses the first order approximation for computing the controller gains based on prior knowledge of channel delays from experiments. Simulation results indicate that the adaptive regulator performs well even when we model the delay via Gaussian distribution. Delay samples obtained from MODBUS over TCP/IP and data-networks are used to illustrate the performance of the controller. The controller is implemented in True Time to illustrate its real-time performance.

Effect of molasses binder on the physical and mechanical properties

引用

International Journal of Minerals,Metallurgy and Materials 2019年第1期26卷 41-51页

作者： Anand Babu kotta Anshuman Patra Mithilesh Kumar Swapan Kumar Karak Department of Metallurgical and Materials Engineering National Institute of Technology

Molasses was used as an alternative binder to the bentonite binder. The change in moisture absorption by pellets prepared with different iron ores and different molasses contents were investigated. Iron ore properties exerted the major effect on pellet behavior and final pellet quality. The absorbed moisture content of pellets prepared without binder, bentonite-added pellets, and molasses-added pellets were in the range of 7.72%–9.95%, 9.62%–10.84%, and 6.14%-6.69%, respectively. The wet pellet compressive strength of molasses-added pellets(43–230 N/pellet) was superior to that of bentonite-added pellets(9.47–11.92 N/pellet). The compressive strength of dried molasses-modified pellets increased to 222–394 N/pellet, which is currently the highest value achieved for dried pellets.

研究了印度奥里萨邦和恰蒂斯加尔邦不同地区铁矿石的化学、物理、热性能和结构特性,了解了Fe、Al_2O_3、SiO_2、S和P的组成变化,分析了其敏感性,以满足各种铁制造工业技术要求。化学分析结果表明,大部分铁矿石中赤铁矿含量丰富(> 90 wt%),矸石含量低(<4.09 wt%SiO_2,<3.8 wt%Al_2O_3),所有铁矿中有害元素含量低(P<0.065 wt%,S<0.016 wt%)。XRD衍射表明矸石以高岭石和石英的形式存在,其傅里叶变换红外光谱(FTIR)在914～1034 cm^(–1)范围内。该铁矿具有优良的物理性能,例如转塔指数(82 wt%～91 wt%)、磨损指数(1.27 wt%～4.87 wt%)和破碎指数(0.87 wt%～1.64wt%)。采用红外光谱和热分析方法对样品进行同化差值分析。研究表明,这些铁矿石具有三个吸热反应,即低于447 K的脱水反应,质量损失为0.13 wt%～1.7 wt%, 525～609 K的脱羟基反应,质量损失为1.09 wt%～4.49 wt%,597～850 K的铝硅酸盐分解,质量损失为0.13 wt%～1.15 wt%。这些铁矿具有优良的物理化学特性,适合高炉和DRI作业。
