模糊自调整PID在锅炉汽包水位中的应用

在锅炉的控制系统中,维持汽包水位在一定的范围内是保证锅炉安全运行的首要条件。传统的控制方式主要采用的算法多是经典的PID算法。提出了用模糊PID参数自调整控制算法实现对汽包水位进行控制的方案,既具有模糊控制灵活而适应性强的优点,又具有PID控制精度高的特点。

Segment that the boiler water level control system is the most significant in the boiler production control system.The traditional control system of boiler adopts the PID algorithm.A scheme using fuzzy PID theory to control drum level has been proposed in this paper.This controller makes the control system which has a good performance by combiningthe good static performance of PID.
