基于DCS的MTO装置反-再系统控制的分析与研究

Analysis and Research on Control of MTO Unit Reaction and Regeneration System Based on DCS

模糊控制最适用于一些大惯性、大滞后、非线性、数学模型难以获得的系统。模糊控制系统的鲁棒性强,干扰和参数变化对控制效果的影响被大大减弱,MTO系统是一个多变量、强耦合的反应控制系统。尝试从工程应用的角度对反应系统变量做了相关性分析,并且对该系统提供了一种先进的模糊PID控制策略。

Fuzzy control is the most suitable for the system of large inertia, large lag, nonlinear, mathematical model that is difficult to obtained.The fuzzy control system has strong robustness, interference and influence parameters on the control effect is greatly reduced, the MTO system is a multi variable, strong coupling reaction control system, this paper attempts to do correlation analysis of reaction system variables from the view of engineering application, and the system provides an advanced fuzzy PID control strategy.
