基于自整定PID的烘干炉温度控制软件设计与仿真

传统的烘干炉温度控制系统在烘干过程中,烘干炉温度保持恒温,并不利于产品整体的烘干,而为了达到更好的效果,其温度应由低到高逐渐升高,以利于溶剂的充分挥发.本文分析了PID控制和模糊控制的优缺点,将PID控制和模糊控制的优点结合起来,采用模糊规则在线整定PID的PK、IK、DK三个参数的模糊自整定PID控制方法.基于模糊自整定PID控制算法的控制系统有相当好的灵活性,能进行数据实时采集、利用模糊PID算法进行处理及控制结果显示等功能,可以获得较高的控制精度.

Design and Simulation of temperature control software for drying oven based on self-tuning PID

The traditional drying furnace temperature control system keeps constant temperature in the drying process, which is not conducive to the overall product, to achieve better results; the temperature should be gradually increased highly full of volatile solvents. This paper analyzes the advantages and disadvantages of PID control and fuzzy control, which combine the advantages of fuzzy control, the fuzzy tuning rules of PID online PK, IK, DK three parameters fuzzy self-tuning PID control method. The fuzzy self-tuning PID control algorithm of the control system based on flexible enough can carry out real-time data collection, using fuzzy PID algorithm for processing the results showed that the function and control, can obtain higher control precision.
