关 键 词：Adaptive PID artificial neuron pH control neutralization reaction 

摘      要：正An adaptive PID controller based on artificial neuron is designed to improve the interference immunity of pH system in acid-alkali *** using the learning algorithm of artificial neuron,parameter self-tuning and adaptability are realized in the control,which solves the problems of long adjustment time,large overshoot and poor anti-interference of PID control in acid-alkali *** results show that the adaptive PID controller has shorter repose time and stronger robustness compared with conventional PID controller.
