The trend of development of automation control in high-speed paper machine
Liu An-jiang · China Pulp & Paper Industry · 2007
An outstanding feature of the automation control in high-speed paper machine is that except the electric drive control system of paper machine, all the other control facilities and their control range must be further expanded in order to form several multi-branched subsystems wherein there exists coordination control. In accordance with the conception of decentralized control and centralized management, the hierarchy of the control system will be much clearer and a mutual independent but running-through-all-system automatic control structure will be formed. The paper introduces the electric drive control system, process control system(PCS), machine control system (MCS), quality control system (QCS), web breaking monitoring system(WMS), paper defects investigation system (WIS) and motor control center (MCC) on high speed and large-sized paper machines.
