摘要
本文介绍一种基于相关系数辨识法的ＰＩＤ（Ｐｒｏｎｏｒｔｉｏｎａｌｐｌｕｓｉｎｔｅｇｒａｌｐｌｕｓｄｅｒｉｖａ－ｔｉｖｅｃｏｎｔｒｏｌｌｅｒ）自动整定算法，以及根据这种算法研制的软件．实际应用表明，本算法鲁棒性强、抗干扰性强；软件操作简单、安全，很适合于实际工业过程的需要．
This paper proposes a PID controller(Proportional plus integral plus derivative controller)auto-tuning algorithm based on correlation cofficient identification approach,and the software developed from that algorithm.In real applications,the alsorithm is proved to be strongly robust,highly antinoise,easy to operate and fit industrial processes.
