一种锅炉燃烧控制的混合智能控制器

针对锅炉燃烧控制系统具有强耦合、多干扰、典型非线性的特点,提出一种理论加经验的混合智能控制方法,将传统PID控制、前馈控制、专家控制相结合,把三种方法的简便性,可靠性,抗扰动快速性、灵活性融为一体,发挥各自的长处,为工业控制开壁一种新途径。该系统成功应用在长沙曙光电子管厂20t/h锅炉控制系统。

A Hybrid Intelligent Controller for a Boiler Combustion Control System

The combustion control system of a boiler is known to have a multitude of specific features, such as a strongly coupled state, being subject to a variety of outside disturbances, typical non linearity, etc. In light of the above a hybrid intelligent control system based on "theory plus experience" is proposed, which combines PID (proportional integral differential) control, feed forward control and expert control. As a result, the simplicity, reliability, anti disturbance, rapid reaction and flexibility of the above three control methods are organically grouped into an integrated whole, giving full play to their respective merits. Initiating a new approach for industrial control technology the system under discussion has been successfully employed for the combustion control system of a 20 t/h boiler installed at Changsha Shuguang Electronic Tube Factory.
