| 摘 要： | 本文中VPSA制氧系统出口流量为双输入单输出非线性系统,难以建立确切的数学模型。但是其中一个输入端即缓冲罐压力可测且不控制其变化量,因此本文对PID神经网络结构进行改进,将其两个输入端增加到三个,使缓冲罐压力作为一个输入端,建立改进的PID神经网络控制器,通过调整网络的权值对调节阀开度调节,进而控制出口流量。

| 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. |
