Method and device for pH control of water supply facilities using tuning method of 2-DOF PID controller by neural network

摘要

The present invention relates to a method and apparatus for pH control water treatment system using a tuning method of the PID controller 2 induced neural network party. ; The present invention can be converted into signals of the measuring water quality of treated water from water analysis instrument of chemicals shares admitted fuzzy variables entered into the drug infusion process model expression of neural networks automatically calculates the drug injection rate of output and settings and by feedback to the error of the output value to modify the result of the equation model from the process of repeatedly learning the process may determine the optimal drug dose, according to these results it is possible to control the drug input valve. ; Water treatment, water quality, adaptive control, PID control, neural networks, neural networks, feedback
