一种基于Fuzzy-PID自整定变参数的控制算法

A Control Algorithm Based on Fuzzy-PID Parameter Seifltuning

本文介绍一种针对油田联合站分离器液位控制的模糊变参数自整定PID控制策略。根据分离器的实际响应，通过模糊规则进行推理和决策，在线整定PID控制器的三个参数，以实现对两分离器液位的优化控制。

Aiming at the separator liquid level control of the muhi-purpose station in oil field, this paper describes the variable parameter self-tuning fuzzy - PID control strategy. According to the actual responses of the separators, the reasoning and the deci- sion-making are conducted by means of fuzzy rules and the three parameters of the PID controller are tuned on-line, so as to realize the liquid level optimum control of the two separators.
