摘要本文研究了非均匀柱模拟移动床过程中基于测量的参数和状态估计问题。提出的估计策略使用的产品流和一个内部流，这是现实的工业应用中的浓度的可用测量。估计任务以分散的方式解决。参数和状态的校正仅针对位于相应测量之前的柱执行。通过产物浓度测量值的偏移来实现收敛。局部估计问题由扩展卡尔曼滤波器解决。该方案被验证为具有非线性吸附等温线的心得安异构体系统。
Abstract In this paper, measurement based parameter and state estimation in Simulated Moving Bed plants with nonuniform columns is investigated. The estimation strategy presented uses the available measurements of the concentrations in the product flows and in one internal flow which is realistic for industrial applications. The estimation task is solved in a decentralized fashion. The correction of the parameters and the state is performed only for the column positioned in front of the respective measurement. Convergence is achieved by the shift of the product concentration measurements. The local estimation problems are solved by Extended Kalman filters. The scheme is validated for a propanolol isomers system with nonlinear adsorption isotherms.
