抄纸过程的BP神经网络PID控制

PID controller of BP nerve network in the copy paper process

为了使抄纸过程的输出(湿度和基重)最大限度地接近给定值,采用BP神经网络PID控制。此控制器由PID控制器和BP神经网络组成,采用BP算法进行PID参数的在线调整,使输出值较好地跟踪了给定值,能达到较好的控制效果,并为抄纸过程的控制提供另一种思路。

In order for the output （ humidity and base weight） in the copy paper process to approximate the given value as much as possible, PI.D controller of BP nerve network is used. The controller consists of PID controller and BP nerve network. BP algorithm is adopted for the on - line adjustment of PID parameters so that the output value traces the given value and good control effect can be obtained.
