Abstract:
      In this paper,the VPSA oxygen-conducting system is a nonlinear system with double inputs and single output,which can not be established a exact mathematical model.But one of the inputs can be measured and can not be controlled,it can be regarded as a input of PID neural network,so an improved PID neural network controller is established,which has three inputs instead of two inputs,and the output will be controlled through adjusting the coefficient.
