基于模糊PID的湿法脱硫系统石膏厚度控制的研究

Research of Gypsum Control of a Flue Gas Desulphurization System Based on Fuzzy-PID

在湿法脱硫系统中二级皮带脱水由于系统的滞后严重,普通PID控制效果并不理想,经理论分析后采用模糊PID复合控制,实现了湿法脱硫系统的控制,并使系统的响应得到了较好的改善,实际应用结果证明了理论的正确性。

The application of Fuzzy- PID control on gypsum dewatefing process is present in Flue Gas Desulphurization （FGD） system, which has not been successful to be dealt with through conventional PID control due to a great lag between action and feedback. The practice results are included to show the effectiveness of Fuzzy- PID Control for the FGD system.
