摘要: 针对汽提塔生产过程具有非线性、强耦合、大时滞及温度难以精确控制的问题,设计了基于变论域模糊PID的汽提塔温度控制系统.选取了基于模糊规则的伸缩因子,将变论域思想和模糊PID相结合,形成变论域模糊PID控制系统结构.分别对常规PID算法、模糊PID算法及变论域模糊PID算法的汽提塔温度控制系统的仿真曲线进行对比.仿真结果表明:变论域模糊PID控制算法有更快的响应速度、更小的超调量和更好的跟踪性能.

Abstract: The stripping process in a stripper is characterized by high nonlinearity, large time delay, strong coupling and that the temperature is difficult to control accurately. A stripper temperature control system based on the variable universe fuzzy-PID was therefore designed. With the scale factor chosen according to fuzzy rules and the concept of variable universe combined with fuzzy-PID, a variable universe fuzzy-PID control system was formed. Then, the three simulation curves of conventional PID algorithm, fuzzy-PID algorithm and variable universe fuzzy-PID algorithm of the stripper temperature control system were compared with each other, and the results showed that the variable universe fuzzy-PID control algorithm has a shorter response time, smaller overshoot and better tracking performance.
