本文分析了PC 機與PLC 的特點，提出由PC 機實現(xiàn)復雜的算法，得到的控制量下傳到
PLC，通過PLC 完成要求的控制功能。這樣，既能容易地加入先進的控制策略與算法，又能可靠、穩(wěn)定地實現(xiàn)控制。本論文以BP 神經(jīng)網(wǎng)絡PID 在溫度控制中的應用為例，通過與Matlab 接口的單片機數(shù)據(jù)采集板，結合AB 公司的SLC5 實現(xiàn)了神經(jīng)網(wǎng)絡PID 的溫度控制。

Abstract: the paper analyses the characteristic of PC and PLC, puts forward an idea that PC
works out the complex operation, and the result transfers to PLC.PLC completes the control
function.It is easy to add the advanced control strategy, also achieve the good result reliably
steadily.For example the BP NN PID in the temperature control system, through the data collect board which can access to Matlab,with AB company SLC5 achieve NN PID control in temperature control system.
