BP-PID在锅炉蒸汽压力控制中的应用

Research on the application in the boiler stream pressure based on BP-PID control

针对锅炉蒸汽压力系统具有大惯性、大滞后等特点,采用BP神经网络PID方法进行控制.该算法简单、易于实现.仿真研究证明该算法具有较好的控制效果.该系统软件在Windows XP平台下利用VB编制,硬件主要由普通PC机和研华的ADAM模块组成.实验证明该系统能实时采集现场压力,具有一定的实用效果.

The BP neural network PID control, which control the boiler steam pressure system due to its is simply calculated and easily realized, is used to large inertia and lag characteristic. The better control effect of the algoithm is confirmed by simulation process. This system software is programmed with VB under Windows XP platform, the hardware are made up of the PC and ADAM modules. Collecting the spot pressure in real-time has been revealed by the experiment,and the praltical effect is acquired.
