| 摘 要： | 针对流化床加热炉传统控制方法落后，成本高，自动化程度低等问题，基于模糊PID控制算法对流化床加热炉的温度进行控制，实现了PID参数自整定，提高了控制精度、效率及过程的稳定性．同时，利用Labwindows／CVI设计了上位机的人机界面．实际运行表明。加热炉内温度稳定时的误差变化幅度小于0.3℃，满足一般流化床加热炉的要求．

| Abstract: | Comparing with the outdated control methods that of high cost and low level of automation,the Fuzzy-PID methods was taken to control the fluidized bed heating oven＇s temperature. PID parameter＇s self-tuning was realized with higher precision and efficiency as well as better stability during controlling process. Simultaneously,the upper computer was designed by Labwindows / CVI. Practical operation shows that the temperature variation is below 0.3℃ when heating oven is in stable state ,which meets the average requirements of the fluidized bed heating oven. |
