[0017] See figure 2 with image 3 As shown, the present invention is a method for boiler drum water level control based on fuzzy neural network PID control. The boiler drum water level control system involved in the method (such as figure 2 Shown) It is composed of a fuzzy neural network PID control system and a boiler drum water supply system; the method includes the following steps:
[0018] Step 1. Analyze the characteristics and modeling conditions of the boiler drum water level control system; specifically: Step 10. Obtain the control object of the boiler drum water level control system and the influencing factors of the control object. The control object is the steam drum and the control object The influencing factors include changes in water supply, combustion, steam load and steam pressure;
[0019] Step 20: Obtain the dynamic characteristics of the steam drum water level control. The dynamic characteristics include: when the feedwater flow of the boiler drum water level ...
