Study on Flue Gas Desulfurization Process Control System Based on Coupling Decoupling Control
2013
The coupling decoupling control system was presented to realize the requirement of the flue gas desulfurization (FGD), to solve the multivariable control problem in this process control system. The FGD experiment control system was designed, the spray flow was controlled by manual and automatic control mode. After the process control flow and the coupling decoupling control principle were studied, the feed-forward compensation control method was simulated. Results show that the decoupling control method could solve the multivariable control problem, with a good anti-interference capacity, meeting the requirement of FGD process control.
