摘　　要：介绍了一种基于CAN现场总线的调节控制仪表的原理和结构,设计了一种基于神经网络的PID自校正控制器,以一个两层线性网络构造PID控制器,通过网络权值的修正,在线地自动整定PID参数。采用CAN现场总线技术,使通信变得更方使一可靠一快速。The structure and principle of a regulable control instrument based on CAN Field bus are introduced in this paper. The design of a PID self-adapting controller based on neural network is discussed, which is created through a two -layer linear network. Through amending network parameters, the PID controller can amend parameters of PID of itself on line. Using CAN Field Bus, the communication of the regulable control instrument becomes more convenient more reliable and faster.
