Application of programmable regulator in the process control of tobacco leaf fermentation

This paper introduces a novel controller for the process control of tobacco leaf fermentation with Double Loop CS910 Programmable Regulator. As a result, higher technological specifications can be met and leaf losses can be reduced. The control system adopts a DCS (distributed control system) structure in which CS910 Programmable Regulators are the lowlevel computers. Each CS910 Programmable regulator is responsible for the process control of tobacco leaf fermentation in one fermentation room, while one high level industrial control computer is used to supervise the work of all the regulators in the whole storehouse. The patterns of cascade temperature and humidity control are also discussed in details in this paper.
