In this work, we consider the monitoring of the absorption column of a typical post‐combustion capture plant within a distributed framework. The column is decomposed into a few subsystems, and a distributed moving horizon state estimator network is designed to estimate the state of the entire column. A state predictor is also designed for each subsystem to approximate the future evolution of the subsystem. These subsystem predictors form a distributed predictor network. Based on the distributed estimator and predictor networks, a fault diagnosis mechanism is proposed specifically for potential additive sensor faults. Extensive simulation results are provided to demonstrate the performance of the proposed approach.

分布式监测燃烧后二氧化碳捕集装置的吸收塔

在这项工作中，我们考虑在分布式框架内监视典型的燃烧后捕集装置的吸收塔。将该列分解为几个子系统，并设计一个分布式移动水平状态估计器网络来估计整个列的状态。还为每个子系统设计了一个状态预测器，以估计子系统的未来发展。这些子系统预测器形成一个分布式预测器网络。基于分布式估计器和预测器网络，提出了一种针对潜在附加传感器故障的故障诊断机制。提供了大量的仿真结果，以证明所提出方法的性能。
