Hydromechanics Research of Pump Flow Control System Based on BP Neural Network PID

Abstract:

In order to improve the accuracy of the pump flow control system,With the application of hydromechanics:the actual flow of the pump is restricted by head,the mathematical model of the fluid flow control system is established.Through the analysis, which obtained three kinds of unit step response curve of the pump flow control when it is under the condition that without using the PID,using the PID and using the BP neural network combined with the PID control. It is concluded that the efficiency of using the BP neural network combined with the PID is much better, Which can improve the pump flow control system's accuracy.
