Abstract

An adaptive PID controller based on artificial neuron is designed to improve the interference immunity of pH system in acid-alkali reaction. By 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 reaction. Simulation results show that the adaptive PID controller has shorter repose time and stronger robustness compared with conventional PID controller.
