造纸过程定量环节容错控制方法研究

A Fault-Tolerant Control Method for Basis Weight Control of Papermaking Process

本文针对造纸过程控制中所使用的定量传感器精度较低和可靠性较差的问题，提出了利用多传感器间的冗余关系，实现对传感器的故障诊断和造纸过程定量环节的容错控制，仿真和实验均证实了该方法的有效性．

In order to solve the problem of low precision and poor reliability of sensors used in papermaking process control, considered the redundancy relations of sensors,we give a new method which can realize the fault detection of sensors, and fault-tolerant control for basis weight control of papermaking process. Simulation and experimental results show its usefulness.
