摘要:气垫式流浆箱存在总压不稳定、纸浆液位波动较大等问题,是导致成纸质量不稳定的关键因素。本文在分析存在问题的基础上,设计了以模糊控制理论与传统PID控制理论相结合的模糊自适应整定PID控制的流浆箱电气控制系统。此系统设计具有良好的动态性能和静态性能,操作简单,运行可靠,解决了系统存在的问题。

Abstract:Instability of total pressure and fluctuation of the stock level in air-cushioned headbox are the key factors causing poor quality of paper product. On the basis of analyzing the problems and combining the theory of fuzzy control and traditional PID control theory fuzzy adaptive setting PID control headbox electric control system was designed. The system had good dynamic performance and static performance, easy and reliable operation, it solved the existing problems of the system.
